Scaling laws for positron production in laser-electron-beam collisions
Artikel i vetenskaplig tidskrift, 2017

Showers of gamma rays and positrons are produced when a high-energy electron beam collides with a superintense laser pulse. We present scaling laws for the electron-beam energy loss, the gamma-ray spectrum, and the positron yield and energy that are valid in the nonlinear, radiation-reaction-dominated regime. As an application we demonstrate that by employing the collision of a > GeV electron beam with a laser pulse of intensity > 5 x 10(21) Wcm(-2), today's high-intensity laser facilities are capable of producing O(10(4)) positrons per shot via light-by-light scattering.
