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…
Calculation of RF-induced Temporal Jitter in Ultrafast Electron Diffraction
Tianzhe Xu, Fuhao Ji, Stephen Weathersby +1
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…
Observation of Skewed Electromagnetic Wakefields in an Asymmetric Structure Driven by Flat Electron Bunches
Walter Lynn, Tianzhe Xu, Gerard Andonian +8
Relativistic charged-particle beams which generate intense longitudinal fields in accelerating structures also inherently couple to transverse modes. The effects of this coupling m…
Single-shot, transverse self-wakefield reconstruction from screen images
N. Majernik, W. Lynn, G. Andonian +3
A single-shot method to reconstruct the transverse self-wakefields acting on a beam, based only on screen images, is introduced. By employing numerical optimization with certain ap…
