Report of Snowmass 21 Accelerator Frontier Topical Group 6 on Advanced Accelerators
C. Geddes, M. Hogan, P. Musumeci +1
The Snowmass 2021 Accelerator Frontier topical group \# 6 on Advanced Accelerator Concepts, covers new R\&D concepts for particle acceleration, generation, and focusing. Based on c…
Positron Sources for Future High Energy Physics Colliders
P. Musumeci, C. Boffo, S. S. Bulanov +14
An unprecedented positron average current is required to fit the luminosity demands of future high energy physics colliders. In addition, in order to access precision-fron…
Recovery time of a plasma-wakefield accelerator
R. D'Arcy, J. Chappell, J. Beinortaite +14
The interaction of intense particle bunches with plasma can give rise to plasma wakes capable of sustaining gigavolt-per-metre electric fields, which are orders of magnitude higher…
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…
