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…
Multi-scale time-resolved electron diffraction: A case study in moiré materials
C. J. R. Duncan, M. Kaemingk, W. H. Li +16
Ultrafast-optical-pump -- structural-probe measurements, including ultrafast electron and x-ray scattering, provide direct experimental access to the fundamental timescales of atom…
A kiloelectron-volt ultrafast electron micro-diffraction apparatus using low emittance semiconductor photocathodes
W. H. Li, C. J. R. Duncan, M. B. Andorf +10
We report the design and performance of a time-resolved electron diffraction apparatus capable of producing intense bunches with simultaneously single digit micron probe size, long…
