Abstract

The LUXE experiment, currently in design and planning, aims to perform analyses of strong-field quantum electrodynamics interactions by colliding the high-quality high-energy EU.XFEL electron beam with a powerful laser. With the ability to collide laser pulses with bunches of $1.5 \times 10^9$ electrons / $1 \times 10^8$ photons at 1Hz, this high-statistics environment presents an opportunity to probe rare interactions in a new parameter space of a novel regime. To do this requires a unique suite of detectors to measure three types of particles, at highly varying fluxes dependent on laser interaction parameters. The detectors measure electrons, positrons, or photons, and balance sensitivity with high dynamic range and hardness to radiation damage. Presented in brief in this note are the function, design, and reconstruction methods of each of these detectors.
