G. Anzivino et al., REVIEW OF THE HYBRID PHOTO DIODE TUBE (HPD) AN ADVANCED LIGHT DETECTOR FOR PHYSICS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 365(1), 1995, pp. 76-82
The HPD is a nonmultiplicative light detector with typical gain of 100
0 to 5000. Its development project, mainly supported by the CERN LAA p
roject and by the INFN group V, was originally intended to find a repl
acement for the photo multiplier (PM) tubes for scintillating fibre ca
lorimeter readout. After five years of development the HPD has become
a versatile light detector, commercially available for everyday use, t
hat can outperform PM tubes in photon counting efficiency and resoluti
on, multi tesla magnetic field operation, uniformity of response, fast
pulse dynamic range, and gain stability. The HPD has also a wide edge
on PMs on pixelization potential and it is getting more and more comp
etitive on timing properties. A review of the HPD performances and its
latest advances are reported.
