The Center for Injectors and Sources builds and operates high performance beam sources for injectors and accelerators.  Our primary mission is the operation of a polarized electron source for the 12 GeV Continuous Electron Beam Accelerator Facility (CEBAF).  We also operate sources and perform research at the Upgrade Injector Test Facility (UITF), the Low Energy Research Facility (LERF), and the Gun Test Stand (GTS).  In support of our mission our work specializes in DC high voltage photoguns operating at extremely low pressures, using high power lasers to reliably producing intense polarized or unpolarized electron beams from photocathodes, and developing instrumentation and diagnostics to characterize these beams.

'''Mission''': To design, build and maintain high performance particle beam sources for injectors and accelerators.  Our core responsibility is the operation of the polarized electron source for the 12 GeV Continuous Electron Beam Accelerator Facility (CEBAF).  Additionally, we operate sources and injectors for the 170 MeV Low Energy Research Facility (LERF), the 10 MeV Upgrade Injector Test Facility (UITF), and the 500 keV Gun Test Stand (GTS).  Our research interests aim at the production of spin polarized electron and positron beams, magnetized beams and beams with orbital angular momentum.  Our work specializes in extreme high vacuum chambers and diagnostics, very high voltage power supplies and electrodes, high power and radio-frequency lasers, robust and efficient photocathodes, and precision polarimetry.

Mission

The Center for Injectors and Sources builds and operates high performance beam sources for injectors and accelerators. Our primary mission is the operation of a polarized electron source for the 12 GeV Continuous Electron Beam Accelerator Facility (CEBAF). We also operate sources and perform research at the Upgrade Injector Test Facility (UITF), the Low Energy Research Facility (LERF), and the Gun Test Stand (GTS). In support of our mission our work specializes in DC high voltage photoguns operating at extremely low pressures, using high power lasers to reliably producing intense polarized or unpolarized electron beams from photocathodes, and developing instrumentation and diagnostics to characterize these beams.
