Large area photomultipliers are widely used in neutrino and astro-particle detectors to measure Cherenkov light in media like water or ice. The key element of these detectors are the so-called "optical module", which consists of a photodetector enclosed in a transparent pressure-resistant container to protect it and ensure good light transmission. Noise pulses at the anode of each photomultiplier strongly affect the performance of the detector. A large study was conducted on noise pulses of large area photomultipliers, considering time and charge distributions of dark pulses, pre-pulses, delayed pulses, and after pulses. The contribution to noise pulses due to the presence of the external glass vessels was also studied, even comparing two vessels of different brands.

Abstract
Large area photomultipliers are widely used in neutrino and astro-particle detectors to measure Cherenkov light in media like water or ice. The key element of these detectors are the so-called "optical module", which consists of a photodetector enclosed in a transparent pressure-resistant container to protect it and ensure good light transmission. Noise pulses at the anode of each photomultiplier strongly affect the performance of the detector. A large study was conducted on noise pulses of large area photomultipliers, considering time and charge distributions of dark pulses, pre-pulses, delayed pulses, and after pulses. The contribution to noise pulses due to the presence of the external glass vessels was also studied, even comparing two vessels of different brands.File | Dimensione | Formato | |
