Abstract: The Laser Und XFEL Experiment (short LUXE) based at DESY, Hamburg is aplanned experiment to study nonlinearity effects in the strong-field QED regimewith high precision.In order to create electric fields stronger than the so-called Schwinger limit, it isplanned to collide a high-intensity laser pulse with either high-energy electronsup to 16.5 GeV or high-energy photons.As a result, non-linear Compton scattering or Breit-Wheeler interactions willtake place, leading to a laser-intensity-dependent shift of the Compton edge andthe appearance of higher-order harmonics in the energy spectrum. One of thechallenges of measuring the Compton energy spectrum in laser-electron-beamcollisions is the expected flux of outgoing Compton-scattered electrons andphotons, ranging from $10^3$ to $10^9$ particles per collision.This contribution will present the simulation-based design of an electronflux-resistant Cherenkov detector prototype, first testbeam results as well asoptical simulation studies. Further optimisation of the various components aswell as reconstruction algorithms will be discussed.
