(English) Feasibility study of Single Photon Avalanche Diodes (SPAD) as focal plane detectors for new generation Cherenkov telescopes
Large area Single Photon Avalanche Diodes are semiconductor devices with sensitivity to the single photon level and a timing accuracy of order 40ps, but a lack of spectroscopic capabilities. Therefore, these devices can be effectively employed in those applications where sensitivity to low light levels and high timing accuracy are at a premium as, for example, in Cherenkov telescopes for ground-based gamma-ray astronomy.
