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…

Focusing of Relativistic Electron Beams With Permanent Magnetic Solenoid
T. Xu, C. J. R. Duncan, P. Denham +6
Achieving strong focusing of MeV electron beams is a critical requirement for advanced beam applications such as compact laboratory X-ray sources, high gradient accelerators, and u…

Single-Shot Ionization-Based Transverse Profile Monitor for Pulsed Electron Beams
Paul Denham, Alex Ody, Pietro Musumeci +3
We present an experimental demonstration of a single-shot, non-destructive electron beam diagnostic based on the ionization of a low-density pulsed gas jet. In our study, 7~MeV ele…
