Experimental verification of space-charge saturation scaling laws in high-gradient photocathode RF guns
Paul Denham, David Garcia, Atharva Kulkarni +4
We investigate the limits of photoemission yield in a high-gradient S-band radiofrequency photoinjector in the space-charge-dominated regime. Using an RF phase-scan technique, wher…

Harnessing Plasmonic Interference for Nanoscale Ultrafast Electron Sources
Alimohammed Kachwala, Mansoure Moeini Rizi, Christopher M Pierce +3
In this paper we demonstrate the use of plasmonic focusing in conjunction with non-linear photoemisison to develop geometrically flat nanoscale electron sources with less than 40 p…
