Classical Electrodynamics Predictions for LUXE and E-320 Experiments with 17 GeV electrons and TW Laser Collision

Abstract

The experiments LUXE at DESY Germany and E-320 at SLAC USA, are aimed to test strong-field QED for 15 +- 3 GeV electrons and TW laser pulses. In concrete both experiments will demonstrate the dominance of nonperturbative physics by which is expected a huge amount of emitted photons. Although one would expect that classical electrodynamics will fail for strong-field conditions, the purpose of this paper is to demonstrate the inverse of it. In fact, here it is presented a theoretical as well as computational methodology based at the theory of Hartemann-Kerman known as classical nonlinear Compton scattering that yields various energy spectra by which one can anticipate the transition from the lowest nonlinearity until scenarios for bunching emission of photons, fact that to some extent will validate the classical electrodynamics, as to make predictions for prospective experiments.
