A co-axial electron gun to generate millimeter-wave RF using the two-stream instability
Autor: V. Pavlenko, Nikolai Yampolsky, Kip Bishofberger, D. Neben
Publikováno v: The Review of scientific instruments. 92(5)
A novel source for broadband millimeter-wave RF is being designed at Los Alamos National Laboratory utilizing the two-stream instability. This RF source offers the potential for consistent output power over a large bandwidth on a single device. The s

Description of longitudinal space charge effects in beams and plasma through dielectric permittivity
Autor: Nikolai Yampolsky, Kip Bishofberger
We develop a universal framework that allows for quickly solving a wide class of problems for longitudinal space charge effects in beams and plasmas in cylindrical geometry. We introduce the longitudinal dielectric permittivity for the beam of charge

Publikováno v: 2020 IEEE 21st International Conference on Vacuum Electronics (IVEC).
A novel source for millimeter-wave RF is being designed at Los Alamos National Laboratory (LANL) utilizing the two-stream instability. This source has the potential for consistent output power over a large bandwidth on a single device [1]. The charac

Using Emittance Partitioning Instead of a Laser Heater to Suppress the Microbunch Instability
Autor: Bruce E. Carlsten, Nikolai Yampolsky, John W. Lewellen, L. D. Duffy, Quinn R. Marksteiner, Kip Bishofberger
Publikováno v: IEEE Transactions on Nuclear Science. 63:921-929
At the Linac Coherent Light Source (LCLS) X-ray free-electron laser, a laser “heater” is used to generate an uncorrelated 20-keV energy spread on an electron beam to suppress the microbunching instability in downstream bunch compressors. Here we
