Quantum radiation reaction in laser-electron beam collisions

arXiv:1503.01009 · doi:10.1103/PhysRevLett.112.015001

Abstract

It is possible using current high intensity laser facilities to reach the quantum radiation reaction regime for energetic electrons. An experiment using a wakefield accelerator to drive GeV electrons into a counterpropagating laser pulse would demonstrate the increase in the yield of high energy photons caused by the stochastic nature of quantum synchrotron emission: we show that a beam of 1 GeV electrons colliding with a 30 fs laser pulse of intensity will emit 6300 photons with energy greater than 700 MeV, the number predicted by classical theory.
