Electron-Positron Pair Generation

OSIRIS 2D PIC simulation of gamma radiation and electron-positron pair production in a head-on collision of ultra-intense laser pulse (2.5 x 10²³ W/cm², 150 fs) with 3.9 GeV electron beam previously accelerated within the plasma channel.

Simulation by M. Jirka using the PIC code OSIRIS@GoLP, visualization by ELI Beamlines
