Abstract: In the field of non-perturbative quantum electrodynamics (QED), ad-vances in high-intensity lasers allow the generation of strong fields incollisions between laser pulses and relativistic electron beams. Thisenables phenomena such as non-linear Compton scattering and Breit-Wheeler pair production to be probed in the laboratory.The study of Compton energy spectra in these collisions is challeng-ing due to the large number and wide range of outgoing particles percollision ($10^3$ to $10^9$). Our study introduces a new detector conceptcombining a segmented gas-filled Cherenkov detector with scintillatorscreens and a camera system. Integrated into experiments such asE320 at SLAC and LUXE at DESY, these detectors allow to resolvethe electron energy spectrum within the required wide dynamic range.This talk presents the results of first beam tests with a prototype anddiscusses techniques to reconstruct the non-linear Compton electronenergy spectrum.
