| Publication Abstract: | A compact DC high voltage photogun with inverted-insulator geometry was designed, built and operated reli-ably at -300 kV bias voltage using alkali-antimonide photocathodes. This presentation describes key electrostatic design features of the photogun with accompanying emittance measurements obtained across the entire photocathode surface that speak to field non-uniformity within the cathode/anode gap. A summary of initial photocathode lifetime measurements at beam currents up to 4.5 mA is presented. | ||
