Multi-Objective Optimizations of High Gradient C-band Photoinjector for High Bunch Charge Applications
M. Kaemingk, P. M. Anisimov, J. M. Maxson +3
The high gradients potentially achievable in distributed-coupling C-band photoinjectors make them attractive for many high brightness applications. Here we discuss optimization res…
Measurement of Spin-Polarized Photoemission from Wurtzite and Zinc-Blende Gallium Nitride Photocathodes
S. J. Levenson, M. B. Andorf, B. D. Dickensheets +7
Spin-polarized photoemission from wurtzite and zinc-blende gallium nitride (GaN) photocathodes has been observed and measured for the first time. The p-doped GaN photocathodes were…
Compensating slice emittance growth in high brightness photoinjectors using sacrificial charge
W. H. Li, A. C. Bartnik, A. Fukasawa +5
Achieving maximum electron beam brightness in photoinjectors requires detailed control of the 3D bunch shape and precise tuning of the beam focusing. Even in state-of-the-art desig…
Four-Dimensional Emittance Measurements of Ultrafast Electron Diffraction Optics Corrected Up to Sextupole Order
M. Gordon, W. H. Li, M. B. Andorf +7
Ultrafast electron diffraction (UED) is a technique in which short-pulse electron beams can probe the femtosecond-scale evolution of atomic structure in matter driven far from equi…
