Advanced Light Source – Lawrence Berkeley National Laboratory, Berkeley, CA

MAESTRO at 7.0.2 is a beamline at the Advanced Light Source that advances angle-resolved photoemission spectroscopy for the study of electronic structure on the mesoscale regime, covering a photon energy range of 20-1000 eV with a resolving power of 20,000-30,000. The beamline is coupled to unique sample preparation and characterization facilities connecting all of the endstations. Berkeley Lab Engineering designed, built and installed the beamline and insertion device.
