Calculation of RF-induced Temporal Jitter in Ultrafast Electron Diffraction

Autor: Xu, Tianzhe, Ji, Fuhao, Weathersby, Stephen, England, Robert Joel

A significant contribution to the temporal resolution of an ultrafast electron diffraction (UED) instrument is arrival time jitter caused by amplitude and phase variation of radio frequency (RF) cavities. In this paper, we present a semi-analytical a

Magnetic Compressors for MeV-UED

Autor: Xu, Tianzhe, England, Robert Joel

Magnetic compressors offer an attractive path toward jitter-free bunch compression in MeV-UED. Compared with RF bunchers, magnetic compressors do not introduce additional timing jitter and can be configured to minimize timing jitter due to upstream e
