Temperature effects on the electron injection in laser-plasma accelerators — •Soeren Jalas, Manuel Kirchen, and Andreas R. Maier — Luruper Chaussee 149 22761 Hamburg GERMANY

In laser plasma accelerators a high power laser generates plasma waves that can sustain accelerating fields on the order of GV/m. When the laser intensity is sufficiently high these waves can break which enables electrons from the plasma background to be trapped and accelerated. Here we show that the temperature of the plasma background can influence the plasma wave and thereby changes the threshold for wavebreaking to occur. Further, using the Particle-in-Cell code FBPIC we show that a finite plasma temperature can benefit the accuracy and performance of simulations.
