The recent advances in high-intensity lasers have enabled the generation of extreme
fields in the laboratory, driving an increased interest in exploring non-perturbative
Quantum Electrodynamics (QED) under strong-field conditions. Two notable aspects
of strong-field QED are non-linear Compton scattering and Breit-Wheeler pair
production. These phenomena can be observed when a high-intensity laser pulse
collides with a relativistic electron beam.
The E320 experiment of FACET-II is designed to probe the strong-field effects in
electron-laser interactions, obtaining first results in the Compton scattering regime.
The LUXE experiment is a similar project, proposed to be built at DESY, Germany,
with the goal of accurately probing this QED regime using novel detector systems.
Our study proposes a detector system for the efficient detection of high-rate
Compton electrons. The “Electron Detection System” employs a segmented
gas-filled Cherenkov detector along with a scintillator screen and camera system and
is about to be tested under `real` physics conditions at E320.
This seminar will present the fundamentals of the LUXE experiment, introduce its
detector systems and show first results of beam tests with the Electron Detection
System. Furthermore, its implementation into the ongoing E320 experiment and the
upcoming measurement campaign will be discussed. It is anticipated that this joint
experiment will provide further insights into quantum processes in high-intensity
electromagnetic fields.
