A high-DC-voltage GaAs photoemission gun: Transverse emittance and momentum spread measurements
We have built a high-DC-voltage photoemission gun and a diagnostic beamline permitting us to measure rms transverse emittance (/spl epsi//spl tilde//sub x/) and rms momentum spread (/spl delta/) ofExpand
