Computing the Paschen curve for argon with speed-limited particle-in-cell simulation
Joseph G. Theis, Gregory R. Werner, Thomas G. Jenkins +1
Upon inclusion of collisions, the speed-limited particle-in-cell (SLPIC) simulation method successfully computed the Paschen curve for argon. The simulations modelled an electron c…
Dispersion and the Speed-Limited Particle-in-Cell Algorithm
Thomas G. Jenkins, Gregory R. Werner, John R. Cary
This paper discusses temporally continuous and discrete forms of the speed-limited particle-in-cell (SLPIC) method first treated by Werner et al. [Phys. Plasmas 25, 123512 (2018)].…
Extremely Dense Gamma-Ray Pulses in Electron Beam-Multifoil Collisions
Archana Sampath, Xavier Davoine, Sébastien Corde +26
Sources of high-energy photons have important applications in almost all areas of research. However, the photon flux and intensity of existing sources is strongly limited for photo…
All-optical density downramp injection in electron-driven plasma wakefield accelerators
D. Ullmann, P. Scherkl, A. Knetsch +16
Injection of well-defined, high-quality electron populations into plasma waves is a key challenge of plasma wakefield accelerators. Here, we report on the first experimental demons…
A Second-Order Symplectic Integrator for Guiding-Center Equations
John R. Cary
This paper had no abstract originally. A second-order symplectic integration algorithm for guiding center motion is presented. The algorithm is based on the Poincaré (mid-point) ge…
