Photocathode behavior during high current running in the Cornell energy recovery linac photoinjector
Photocathode behavior during high current running in the Cornell energy recovery linac photoinjector
The Cornell University energy recovery linac (ERL) photoinjector has recently demonstrated operation at 20 mA for approximately 8 hours, utilizing a multialkali photocathode deposited on a Si substrate. We describe the recipe for photocathode deposition, and will detail the parameters of the run. Post-run analysis of the photocathode indicates the …
