Our design is based on deep diffused, high gain avalanche photodiodes (APDs) which give a signal of ~6000 e when traversed by 7 Teravolt protons. We observe pulse risetimes of 650 psec and a pulse width of 5 nsec and calculate a time resolution of ~10 psec and a maximum count rate of >100 Mhz.6 Pages, 3 figuresInstrumentation and DetectorsHigh Energy Physics - ExperimentNuclear Experimenttext
