Abstract
The Naval Postgraduate School (NPS) has begun the
design and assembly of the NPS Free-Electron Laser
(NPS-FEL). As part of this effort, the original DC gunbased
injector system from the Stanford Superconducting
Accelerator has been moved to NPS and is being
refurbished and upgraded to operate as a photoinjector.
Design work has begun on a new, SRF, quarter-wave
resonator based cavity that can serve as either an energy
booster or photocathode gun.
The overall NPS-FEL design parameters are for 40-
MeV beam energy, 1 nC bunch charge, and 1 mA average
beam current, built as an energy-recovery linac in its final
configuration [1]. As we move towards this goal, the
injector system will be incrementally upgraded to add
photocathode capability, have a higher final beam energy,
and improve the beam brightness, to meet the needs of the
overall experimental program.
