Abstract

Artificial sapphire gained interest as radiation detector in the recent years, as an alternative to diamond. The research and development campaign to design, build and characterize a radiation-hard detector for gamma beam monitoring takes place in the scientific context of the Laser Und XFEL Experiment (LUXE) at DESY. The experiment requirements of beam profile reconstruction with micro-metric precision and radiation hardness led to a proposed sapphire microstrip detector design. This work introduces the scientific context for a sapphire microstrip gamma beam profiler (GBP) and describes the experimental campaign for sapphire characterization from early prototypes to the final development of a 192-strip detector.
