Strong-Field Quantum Electrodynamics (SFQED) is an emergent field of physics, where conventional quantum electrodynamics calculations become non-perturbative due to a strong electromagnetic background field. This gives rise to non-linear Compton scattering and non-linear Breit-Wheeler pair production. Advances in laser technology have made it possible to explore this field, by colliding photons from a high-intensity laser with a high-energy electron beam. One of the experiments that will measure SFQED phenomena is LUXE, an experiment planned at DESY. Part of LUXE is its electron detection system (EDS), which will measure high rates of electrons coming from electron-laser interactions. It consists of a segmented straw Cherenkov detector, and a scintillator screen and camera set-up. A prototype of the EDS has recently made measurements with E320, an SFQED experiment at the FACET-II facility at SLAC, where it measured non-linear Compton scattering. This talk will discuss the prototype of the EDS and the first results obtained from the measurements at E320.
