In Remembrance of James (Jim) E. Galvin, 1945 – 2021

By Will Waldron, Joseph Chew and Kathy Bjornstad

James (Jim) E. Galvin, Sr. Electronics Engineering Associate, in Berkeley Lab’s Engineering Division, passed away March 3, 2021 at age 76.

Even at a lab known for long careers and for the invaluable technologists and engineers who help make team science happen, Jim’s accomplishments and dedication stood out.  Across 42 years of service at the Lab, (and he continued as a retired affiliate part time, over the course of the past 7 years), he contributed to efforts that ranged from energy-efficient lighting to neurons on a chip.  He was associated longest and most closely with ion-source development and applications in ATAP’s predecessor, the Accelerator and Fusion Research Division.

Jim’s contributions in retirement continued as he assisted the Ion Beam Technology Program, the NDCX-II heavy-ion accelerator facility, and the ALS Upgrade Project.  Over the last several years, Jim’s contributions have been critical to the MOSFET-based inductive voltage adder pulsers used to drive the stripline kickers that will be crucial to ALS-U.

It was the culmination of a career that began in 1971, when he was recruited to work on a team led by another Berkeley Lab engineering legend, Bill Baker, that was developing neutral-beam injection systems for heating and plasma confinement in magnetic fusion energy experiments.  Jim’s other early efforts included helping develop ion sources for the SuperHILAC, a heavy-ion linear accelerator famed as the discovery site of several elements.

Jim developed broad experience with RF and pulsed electronics as well as with careful measurement techniques—an invaluable skill set at an accelerator lab.  He also amassed a vast collection of microscope hardware, light calibration equipment, and electronics calibration equipment, which he used to help many groups take high-quality measurements.

His interest in optics led him to the Windows and Daylighting Group in what was then the Energy and Environment Division, which needed precision measurements of light.  Among other contributions, he was an early adopter of high dynamic range (HDR) techniques, now familiar in consumer products but then at the cutting edge.

In a crossover from his usual work for Ian Brown in the Plasma Applications Group, he also contributed his imaging skills to Life Sciences Division researchers with the Neural Matrix CCD.  A spinoff of the group’s work on biocompatible diamondlike-carbon (DLC) coatings, it enabled biologists to  learn how neurons in the human nervous system communicate.  Other potential uses for this technology include cultivating interconnected nerve cells for testing drugs, or for sensing toxins, and someday it may even play a role in restoring the use of limbs and eyesight.  The development was honored with an R&D 100 Award in 2005 and one of the five patents on which he was a co-inventor.

Jim had particular expertise in designing low-noise instrumentation and RF amplifiers. His career spanned the years from analog to the advent and growth of digital technologies. The latter became more and more prominent, and he eagerly embraced these new developments.  He became a prolific designer of a wide variety of printed-circuit boards for many applications, from early field-programmable gate array (FPGA)-based digital electronics to custom high-voltage switching electronics and diagnostics.

Jim’s professional interests in optics and imaging, as well as his friendliness and willingness to help others, carried over into his personal life, where he introduced many people to the wonders of science.  Not even the urban lights and frequent cloud cover of the inner Bay Area deterred him from sidewalk astronomy and the accompanying public outreach at his home in the Watergate Emeryville complex. He also helped organize art shows at the Watergate’s Clipper Club, and was known for generously sharing his time, expertise, and high-tech tools and toys.    

The dark nighttime skies, clear dry air, and unique scenery of Death Valley saw several of Jim’s interests in full flower.  Spending one or two months there every winter, he became the unofficial scientist-in-residence of the Stovepipe Wells Hotel, showing other visitors the secrets of the night sky or switching to a microscope to examine minerals. 

As Jim recalled, “One night I had my telescope set up on the moon, and many people stopped by.  One said she had a group of geology students, camping across the road, and asked, could they look.  Of course!  So the next night they started arriving.  There were 45 high school students.  There were clouds, but I had brought a differential interference contrast or Nomarski microscope, so I showed them protozoa and bacteria from Salt Creek.  I also showed them crystals with polarized light.  The next night was clear, so I showed them the moon and the pics I had taken of the Orion Nebula and the Andromeda Galaxy.  They were amazed.  As they were leaving a few days later I went over to their camp and gave their leader some of my postcards.  She thanked me, and I got a round of applause.  They wanted to make sure I would be there next year.”

By day as well as night, Death Valley was also an inspiring location for one of his other passions, photography, including large-format work.  Several of his pictures are on display at the hotel.  So many people have expressed their appreciation of working with Jim and his love of science and discovery.  A life well lived, and he will be missed by many.

Henrik von der Lippe Takes on Second Role as Lab Chief Engineer

Based upon materials by Glenn Roberts, Jr., Berkeley Lab Strategic Communications

Henrik von der Lippe, director of the Lab’s Engineering Division since 2016, has been appointed to also serve in a newly created role as Laboratory Chief Engineer. Von der Lippe was appointed to the role for an initial two-year term.

The Lab-wide position seeks to build more synergy among the Lab’s engineering capabilities, and to provide more direct ties between the engineering community and the Directorate, which will help ensure close coordination in furthering Lab initiatives in safety, diversity, and recruitment, among others.

The new position will also facilitate common approaches to engineering processes across Lab areas, divisions, and groups, and will advocate for new tools and processes benefiting the engineering community.

“At the end of two years, if we have a uniform way of doing engineering at the Laboratory I think that would be a spectacular result,” von der Lippe said of the opportunities presented by the Chief Engineer role.

“Traditionally, engineering at the Lab has been focused on supporting large projects in the Physical Sciences Area, and of course for the Advanced Light Source and the ALS-Upgrade,” said Horst Simon, Lab Deputy Director for Research.

“But engineering skills, tools, and methodology are things that we need to apply Lab-wide. Henrik’s new role is to demonstrate that engineering is a Lab-wide capability that should be there for all scientific areas, similar to Information Technology and the Office of the Chief Information Officer.

Von der Lippe, who joined Berkeley Lab as a staff engineer in 2007 and served as deputy director for the Engineering Division from 2007-2015, noted that the division mostly supports the Lab’s scientific community by building instrumentation for experiments.

The Lab’s Facilities and Project and Infrastructure Modernization divisions, meanwhile, have engineering capabilities to carry out construction projects, for example.

One of his goals for the new Chief Engineer role is to “bring the engineering community closer together – right now it’s more fragmented,” von der Lippe said. “There are a lot of engineers here who could learn from each other and help each other.”

Transit to Operation (TTO) for LCLS-II Injector Source

Based upon materials by Glenn Roberts, Jr., Berkeley Lab Strategic Communications

The electron gun fired its first electrons May 29, 2019. Since then, Berkeley Lab personnel have been working with their SLAC counterparts to commission the full injector source, an effort that continues so that it reaches its full performance expectations. The TTO required that it meet a set of threshold parameters en route to the final goals. The Berkeley Lab injector source for Linac Coherent Light Source-II has been formally accepted through a Transition To Operations (TTO) memorandum. The event marks the end of a highly successful multi-year effort to build this extremely challenging part of LCLS-II.

Remembering U.S. Particle Accelerators Expert Tom Elioff

Known for his deep expertise and skillful management of large projects, an engaging and effective way of working with people, and an abiding love of fishing and hunting, Elioff’s accomplishments stretched over nearly half a century.

He worked on early accelerators at Berkeley Lab, including the Bevatron and 184-Inch Cyclotron, and he worked directly with Nobel laureates including Edward McMillan – whom he considered an important mentor – and Ernest O. Lawrence, Owen Chamberlain, and Emilio Segrè.

Elioff was instrumental in the construction of the PEP and PEP-II particle colliders at SLAC, worked on the Superconducting Super Collider (SSC), and after retiring from Berkeley Lab came back to SLAC to manage construction of the SPEAR3 particle storage ring, which was brought in three months ahead of schedule. 

“He really loved the building of these things – watching them come together, with all of their different components,” recalled Amanda Elioff, Tom’s daughter, who is an engineering manager in the Los Angeles area for WSP, a large engineering and design firm. “As well as the physicists, he enjoyed working with the other disciplines – particularly the engineering groups – he had really special relationships with the people who worked in the fabrication shops. I think the feeling was mutual.”

Amanda recalled his tireless work ethic, too. “He was working nonstop,” she said. There was a time when he would drive from Oakland to Menlo Park daily, and stints where he also had to spend time away from family for the work week and return on weekends.

When it came to her studies, “He helped me succeed. He would stay up until midnight with me, helping me with my math homework. I was amazed he could remember how to do calculus. He felt strongly about the advancement of technology and science.” And her father and mother, Ione, impressed upon her the value of an education in science and engineering.

She recalls childhood visits to Berkeley Lab and marveling at “all these dials, green screens, and wires” filling the control room of the Lab’s giant cyclotron.

“He was such a great guy,” recalled SLAC’s John Seeman, who worked with Elioff on the PEP-II project. “He worked very hard, was always thinking of what needed doing next, was a straight shooter, and always kept the project first rather than himself. He worked on more accelerators than anyone else I know. He always had good things to say about everyone, but kept them on a true course.”

Fishing and physics

Tom “Tommy” Elioff was born Dec. 11, 1933 in Monroe, Louisiana, to Elisa and Michael Elioff, who had immigrated from Bulgaria. His father worked as a welder on natural gas pipelines, and “often came home with parts of his khaki clothing burned away,” Elioff recalled in an autobiographical booklet he and his wife put together in 2014. His father started taking him out into the bayous to fish when he was 5 or 6 – the start of a lifelong passion for fishing – and he tended chickens, worked in his mother’s large garden, and joined a family-wide effort to help his older brother, Bob, recover from polio.

During World War II, Elioff made friends with pilots training at nearby Selman Field and began building free-flight and radio-controlled model planes, winning a competition with a plane that reached 160 mph. In high school he gravitated toward math and science classes, played baseball and softball, participated in drama and debate, and began dreaming of getting a Ph.D. in physics from UC Berkeley. 

Elioff got his bachelor’s degree in 1954 from Louisiana Polytechnical Institute, where he met his future wife, Ione Hill; they would marry in 1956 after she received her master’s degree from the University of Tennessee.

Then, with a Phi Kappa Phi scholarship making it possible to fulfill his dream, he started graduate studies at UC Berkeley.

Model airplanes and big accelerators

Elioff immediately went to visit the university’s Radiation Laboratory, which eventually would become known as Berkeley Lab, and sought out the lab’s director, Ernest O. Lawrence. Lawrence didn’t ordinarily allow first-year grad students to work with the Lab’s accelerators, but when he heard that Elioff had built model airplanes and repaired bicycles, he declared the young man a perfect fit, Elioff later recalled.

He began helping the team of engineers that ran the lab’s 184-inch cyclotron, including arranging beamlines used to treat cancer patients, and in his spare time went mountain climbing – a hobby learned from his new European colleagues in Berkeley – took up skiing, and helped out on a commercial salmon fishing boat, the Lucky Day.

Fishing “and the camaraderie of fishing and hunting – were his other passions,” Amanda said. She noted that her father had a special group of friends outside of work circles whom he spent time with hunting, fishing, and playing poker. Amanda recalled that her father also advocated later in life for salmon conservation efforts.

He also assisted with experiments at the lab’s Bevatron synchrotron that discovered the antiproton and led to a Nobel prize in Physics for Segrè and Chamberlain in 1959. 

After receiving his Ph.D. in 1960, Elioff continued to work at the Bevatron, where he 
led development and construction of 10 external beamlines, created an experimental users group, and wrote a handbook. He was appointed to the Berkeley Lab senior staff in 1966.

In 1970 Elioff took a two-year leave to work for the Atomic Energy Commission, which oversaw the national labs that would later become part of the U.S. Department of Energy. There he oversaw the Fermilab construction program as well as development at other accelerator labs. 

Returning to Berkeley Lab in 1973, he served as a group leader in the Accelerator and Fusion Research Division and then as the division’s deputy director.

Particle collider projects 

It was in 1977 that he first became involved in projects at SLAC. The first one was PEP, the Positron-Electron Project, which had five detectors to record what happened when accelerated electrons and positrons collide. Building PEP was a joint Berkeley Lab and SLAC project, and he served as deputy director. 

Pier Oddone, a former Berkeley Lab physicist and deputy director who was director of Fermilab from 2005 to 2013, said, “I worked closely with Tommy in the first incarnation of PEP in the 1970s.  He was in charge of the conventional facilities, and I was the coordinator for the experimental program that used those facilities. Tommy was already an experienced manager and I was still wet behind the ears in my first significant management job. We developed a great working relationship. I learned many useful skills from him.”

When that work was completed in 1980, Elioff returned to Berkeley Lab, where he directed the National Center for Advanced Materials and led a group that worked on conceptual design and cost estimates for the Advanced Light Source synchrotron.

The SSC years

In 1984, when planning began for the Superconducting Super Collider – an underground proton collider that would have been 54 miles around, twice the circumference of today’s Large Hadron Collider in Europe – Elioff got involved from the start, representing Berkeley Lab on the Central Design Group and serving as head of project planning and management. He went on to work for three years on the next stage of accelerator development at the SSC construction site in Texas, where his daughter Amanda, was also working on the project as a civil engineer for Parsons Brinkerhoff (now WSP).

“It was really great to be able to spend more time with my dad” Amanda Elioff said of their time in Texas. “He lived in a hotel and he would come over to my apartment in Dallas and we would go out for oysters and beer.”

Also, Ione had moved south during that time to take a job as president of Delgado Community College in New Orleans.

But with construction well underway, Congress shut down the project in 1993. The cancellation of that project “really affected” her father, Amanda said, because he had invested so much effort in it.

Building a B Factory

Tom Elioff returned to Berkeley Lab, only to be invited back to SLAC a year later by Jonathan Dorfan, director of the PEP-II project, to become deputy director of the project – another collaboration between SLAC and Berkeley Lab along with Lawrence Livermore National Laboratory.

This upgrade to the PEP collider added a new low-energy ring to accelerate positrons above the existing high-energy ring, which accelerated electrons. Meanwhile, a consortium of nine nations designed and built a 1,200-ton particle detector known as BaBar to record the results of interactions. Pep-II an BaBar were collectively known as the B Factory, designed to produce and record large numbers of B meson particles for a range of studies, including exploring the still-unanswered question of why there is more matter than antimatter in the universe.

PEP-II was dedicated in 1998, and in 2000 the project team received the DOE Program and Management Award.

“Tom was an uncommonly wonderful man with whom we at SLAC had the great honor of sharing a long, and highly fruitful, collaboration,” said Dorfan, who went on to serve as director of SLAC. “Decency, integrity, and humanity were complemented by Tommy’s exceptional technical and management skills. Everybody loved Tommy – how could one not? He had a uniquely effective way of breaking down complex problems and selecting practical and convincing solutions. This proved invaluable when dealing with Washington.”

In short, Dorfan said, “Tommy was the ideal leader for a federally funded construction project, as his countless successes in such roles proved.”

Upgrading a synchrotron at SLAC

Elioff returned to Berkeley Lab in 1998 and formally retired after 44 years at the Lab between 1955-2004. But he had one more adventure ahead – his “last accelerator hurrah,” he called it – and once again, it took him to SLAC, where Director Burton Richter asked him to direct the SPEAR3 project, which would upgrade the 30-year-old storage ring at the heart of the Stanford Synchrotron Radiation Lightsource (SSRL). 

Keith Hodgson, a professor at Stanford and SLAC who was then director of the Synchrotron Division at SLAC, recalled meeting Elioff in 1999, just after the project was funded by DOE and the National Institutes of Health.

“Tom was a remarkable person – one of those people who just had an aura about him,” Hodgson said. “He was a very gentlemanly, kindly soul; genuinely warm, kind of low-key, and also an excellent mentor. It was pretty obvious that Tom was just fantastically talented and exactly the kind of person we needed to lead the SPEAR3 project and make it successful.”

The project was completed three months ahead of schedule, with only an 11-month interruption in user operations for the major installation, and within its budget. In 2004, then-DOE Secretary Spencer Abraham presented the project management team with the Secretary’s Excellence in Acquisition Award.

“Tom brought a very special quality to the project,” said Robert Hettel, who was Elioff’s deputy on the project and now directs the upgrade to the Advanced Photon Source at Argonne National Laboratory. 

“He was very experienced in large projects; well-known and respected by DOE; trusted by Burt, Jonathan, and SLAC because of cooperative relationships over decades; and, perhaps most importantly for the SSRL team, bringing project directorship with a light hand and a certain Southern genteel demeanor that inspired us. He was and is a role model for me to this day,” Hettel said.

In objective terms, Hettel added, SPEAR3 was not a huge project, “but for us, SPEAR3 was really big potatoes,” adding a suite of improvements that initiated a new phase of operations for SSRL and rejuvenated X-ray science at SLAC.

At the SPEAR3 dedication in 2004, which marked the end of Elioff’s full-time accelerator work, Pat Dehmer, then director of DOE Basic Energy Sciences, presented him with the DOE Distinguished Associate Award for “many accomplishments and leadership in the project management of major accelerator construction for the Department of Energy” over nearly half a century.

Eiloff is survived by his wife, Ione Elioff of Berkeley; and daughter Amanda Elioff of Pasadena.

Services have not yet been announced. The family will be donating to Phi Kappa Phi in his memory.



In Remembrance of Donald Landis, 1933-2019

Donald A. Landis passed away on January 11, 2019 at the age of 85. He began his employment at the Lab in 1959 and retired as a Senior Staff Electronics Engineer in the Engineering Division in 1991. Though formally retired, after a short break, Don continued his affiliation with the Lab until 2016. Don, a native of California, began his electronics career in the U.S. Army where he was placed in the Signal Corps. While in the Army, Don was deployed to Germany to help rebuild the German phone system after the war. After finishing his tour in the Army, Don began pursuing a BS in Electrical Engineering UC Berkeley. After graduating in 1959, Don joined the Laboratory’s Nuclear Chemistry and Physics Instrumentation Group (headed by Fred Goulding), which became the Department of Instrument Science and Engineering (DISE) and is now the Electronics, Software & Instrumentation Engineering (ESIE) Department.

Under Goulding’s mentoring, Don completed his Master’s Degree in 1961 and developed expertise in low-noise preamplifiers and associated amplifiers with an emphasis on pulsed-feedback techniques. He was also affiliated with the development of semiconductor particle and energetic photon detectors in support of nuclear physics and nuclear chemistry. His expertise became a unifying theme of his long and distinguished career at the Laboratory. In the early 1960s, Don started designing detector instrumentation that was eventually used in all of the Berkeley Lab accelerators.

This was a particularly dynamic period in Laboratory history. The 88-Inch Cyclotron had recently been commissioned, the search for transuranic elements was actively being pursued at the HILAC, and the Bevatron was at the peak of its productivity as a premier facility for elementary particle physics. Don’s development of electronics for experimental physics and nuclear chemistry was a welcome addition to the Laboratory and later for Biophysics experiments.

Don’s importance to the Lab was highlighted by the many contributions he made through the direct support of the nuclear chemistry and physics research staff. His instrumentation was used to study the properties of heavy elements (transuranics produced at the HILAC and SuperHILAC), nuclear structure and reactions (HILAC, 88” Cyclotron and 60” Cyclotron at the Crocker Lab on campus), exotic atoms (Bevatron), and heavy ion beams for biophysics (Bevalac). Some of the more noteworthy projects were the: 198 counting system, particle identifier system, beam integrators at the 88″ cyclotron, mirror position measuring electronics for the Keck 10 Meter Telescope, first Time Projection Chamber analog pulse processing electronics with discrete components, and signal processing electronics for the Iridium anomaly coincidence spectrometer that played a key role in developing the argument that an asteroid collision caused the extinction of dinosaurs 65 million years ago. Don also played a key role in developing the signal processing electronics for the GammaSphere, for the Princeton Tokamak X-ray spectrometers, and for the 76^Ge double beta decay experiment, to name a few.  

Don Landis won the respect of a varied group of collaborators with whom he worked and the gratitude of dozens of colleagues whose careers he enhanced. His achievements were recognized across the international scientific community. Even though Don retired from the Lab in 1991, he continued to contribute to the GammaSphere experiments at the 88” Cyclotron for many years.

Don is survived by his wife Joan, son Mark, daughter Laurie and grandchildren and great-grandchildren. A Celebration of Life service was held on February 3, 2019 at the El Sobrante United Methodist Church.
