Achieving 50 femtosecond resolution in MeV ultrafast electron diffraction with a double bend achromat compressor
Fengfeng Qi, Zhuoran Ma, Lingrong Zhao +12
We propose and demonstrate a novel scheme to produce ultrashort and ultrastable MeV electron beam. In this scheme, the electron beam produced in a photocathode radio-frequency (rf)…

Single shot cathode transverse momentum imaging in high brightness photoinjectors
Peng-Wei Huang, Houjun Qian, Ye Chen +18
In state of the art photoinjector electron sources, thermal emittance from photoemission dominates the final injector emittance. Therefore, low thermal emittance cathode developmen…

An Analytical Approach to Eddy Current in Electromagnetic Damping
Hao Chen, Yawen Xiao, Jinze Shi +1
An analytical method of calculating eddy current in a metallic spinning gyroscope in external magnetic field is presented. With reasonable assumptions, the problem is simplified fr…
