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…
A note on the experiment parameters for the non-resonant streaming instability: competition between left and right circularly polarized modes
Chun-Sung Jao, Sergei Vafin, Ye Chen +10
A non-resonant streaming instability driven by cosmic-ray currents, also called Bell's instability, is proposed as a candidate for providing the required magnetic turbulence of eff…
Passive Ballistic Microbunching of Non-Ultrarelativistic Electron Bunches using Electromagnetic Wakefields in Dielectric-Lined Waveguides
Francois Lemery, Philippe Piot, Gayane Amatuni +14
Temporally-modulated electron beams have a wide array of applications ranging from the generation of coherently-enhanced electromagnetic radiation to the resonant excitation of ele…
Generation of quasi continuous-wave electron beams in an L-band normal conducting pulsed RF injector for laboratory astrophysics experiments
Ye Chen, Gregor Loisch, Matthias Gross +8
We report on an approach to produce quasi continuous-wave (cw) electron beams with an average beam current of milliamperes and a mean beam energy of a few MeV in a pulsed RF inject…
Studies on charge production from Cs2Te photocathodes in the PITZ L-band normal conducting radio frequency photo injector
C. Hernandez-Garcia, M. Kraslinikov, G. Asova +20
This paper discusses the behavior of electron bunch charge produced in an L-band normal conducting radio frequency cavity (RF gun) from Cs2Te photocathodes illuminated with ps-long…
