LUX-ZEPLIN (LZ)

Sanford Underground Research Facility (SURF), Lead, South Dakota

The LUX-ZEPLIN (LZ) experiment utilizes 7 tonnes of active liquid xenon to search for xenon nuclei that recoil in response to collisions caused by an impinging flux of dark matter particles known as WIMPs (Weakly Interacting Massive Particles).  The experiment will be located nearly 1 mile underground in the Sanford Underground Research Facility (SURF) in Lead, South Dakota. The active liquid xenon is configured in a cylinder 1.5 meters in diameter and height, with an applied electric field to form a TPC (Time Projection Chamber).

ALS-U

High voltage pulsers are required to drive fast kicker magnets which will inject and extract beam to and from the ALS-U storage ring. This inductive voltage adder with MOSFET's produces fast rise and fall times on the voltage pulses that are required so that only the target bunches are deflected.

Advanced Light Source (ALS), Lawrence Berkeley National Laboratory, Berkeley, CA

ALS-U is a planned upgrade of the Advanced Light Source (ALS) at Berkeley Lab that will provide revolutionary x-ray capabilities. The ALS has been a global leader in soft x-ray science for more than two decades. Recent accelerator physics breakthroughs now enable the production of highly focused beams of soft x-ray light that are up to 1000 times brighter than that of the existing ALS. Applying this technology at the ALS will help us to better understand and develop the new materials and chemical systems needed to advance our energy, economic, and national security needs in the 21st century, securing the United States’ world scientific leadership for decades to come.

STAR Heavy Flavor Tracker

STAR Heavy Flavor Tracker

Brookhaven National Laboratory, Upton, NY

The Heavy Flavor Tracker (HFT) is a vertex detector which is part of the STAR (Solenoid Tracker at RHIC) detector located at the RHIC (Relativistic Heavy Ion Collider) accelerator. The HFT detector is designed to detect particles containing heavy quarks my measuring their extremely short decay vertexes. It consists of 4 silicon detection layers; the inner two layers are PXL, followed by IST and SSD as the outer layer. PXL uses novel pixilated sensors with high resolution and low mass that achieve breakthrough performance results. IST and SSD are used to point the tracks between PXL and the STAR TPC (Time Projection Chamber). Scientists and engineers at Berkeley Lab have played a major role in the design of both PXL and SSD.
