Sc. Hartman et al., INITIAL MEASUREMENTS OF THE UCLA RF PHOTOINJECTOR, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 340(1), 1994, pp. 219-230
The 1.5 cell standing wave rf photoinjector has been operated for the
past several months using a copper cathode. The photoinjector drive la
ser produces sub 2 ps pulses of UV (lambda = 266 nm) light with up to
200 muJ/pulse which generates up to 3 nC of charge. The emittance of t
he photoinjector was measured as a function of charge, rf launching ph
ase, and peak accelerating field. Also, the quantum efficiency and pul
se lengths of the laser beam and the electron beam were measured.
