Charge lifetime measurements at high average current using a K_{2}CsSb photocathode inside a dc high voltage photogun
Two K_{2}CsSb photocathodes were manufactured at Brookhaven National Lab and delivered to Jefferson Lab within a compact vacuum apparatus at pressure ∼10^{-11} Torr. These photocathodes were evaluated using a dc high voltage photogun biased at voltages up to 200 kV, and illuminated with laser light...
