Abstract: (Elsevier)
Si pad sensors with 256 cells have been used to detect single photoelectrons from a CsI photocathode. These sensors are part of a Hybrid Photon Detector (HPD) to be used in a RICH detector in the LHC-B experiment. The I - V and C - V measurements are presented. The pad sensors are read out with the low-noise VA2 chip. Results from tests with these detectors with a 90 Sr source are reported. Measurements of photoelectrons created by 160 nm wavelength photons in a CsI cathode in a test set-up are also reported. Finally, the prospects of using such sensors with fast LHC readout electronics are discussed.- talk: Rome 1996/06/17
