P. Hartmann et al., PICOSECOND POLARIZED ELECTRON BUNCHES FROM A STRAINED-LAYER GAASP PHOTOCATHODE, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 379(1), 1996, pp. 15-20
dAt the Mainz electron accelerator MAMI a facility has been set up tha
t allows the measurement of the bunchlength, the energy spread and the
averaged and phase resolved polarization of picosecond electron bunch
es from a source of polarized electrons for MAMI. Electron bunches of
typically 10 to 30 ps duration are generated by illuminating a straine
d layer GaAsP photocathode with femtosecond laser pulses.
