ABSTRACT

High-energy physics (HEP) experiments have already been important driving forces for the development of detector technologies, and planar crystalline silicon sensors developed for track nding and particle analysis are now mature detector technologies commercialized in many areas of science and medicine.1 Alternatives to the state-of-the-art hybrid pixel silicon detectors are now developed to greater maturity to improve detection performance, to prot from different technology specicities, or to lower costs for future HEP experiments2,3 and for other detection applications. Since the late 1980s, alternative detector technologies based on amorphous
