Description
To study the temporal response of NEA-GaAs polarized photocathode systematically, we have developed a longitudinal profile measurement system for 20-keV electron beams using a deflector cavity. The measurement resolution is estimated to be 0.7 ps and the transmission-type strained superlattice photocathode was used as a test sample. The pump laser, with pulse width around 7.2 ps rms including time jitters was irradiated onto the photocathode. The electron bunch length and the temporal decay constant were evaluated to be 10.4 ps rms and 6.1 ps, respectively. (author)
