, 2017 This handbook is aimed at helping users of PMTs who are faced with the challenge of designing sensitive light detectors for scientific and industrial purposes. The raison d’être for photomultipliers (PMTs) stems from four intrinsic attributes: large detection area, high, and noiseless gain, and wide bandwidth.

Comparison of a silicon photomultiplier to a traditional vacuum photomultiplier
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005Silicon photomultiplier devices (SiPM) were investigated as a possible front-end detector system for the electromagnetic barrel calorimeter of the GlueX Project at Jefferson Laboratory, USA, and compared against a traditional 2 in vacuum photomultiplier tube.

Potentialities of silicon photomultiplier
SPIE Proceedings, 2014The Silicon Photomultiplier (SiPM) is a novel pixelated photon detector able to detect single photon arrival with good timing resolution and high gain. In this work we present a complete study of the performances of different SiPMs produced by STMicroelectronics.

A SIMPLE PHOTOMULTIPLIER PHOTOMETER
Journal of the Royal Microscopical Society, 1956SYNOPSISThe great sensitivity of photomultipliers offers many advantages over photocell‐amplifier systems for the measurement or comparison of low levels of illumination. However, a highly stabilized power supply is generally considered to be essential. Tests have shown that for many purposes such supplies are not necessary.

Applied Optics, 1985
Dark pulse distributions from three types of photomultiplier have been fitted to Poisson distributions, both for pulses originated by single electrons and for larger pulses. These distributions can be used to determine the first-dynode secondary-emission coefficients, the fraction of electrons that create positive ions, the number of secondary ...

Refrigeration for Photomultipliers
Applied Optics, 1966A closed-cycle mechanical refrigeration system has been adapted to cool photomultipliers automatically. Temperature is adjustable between +50 degrees and -55 degrees C and is stable to within +/-0.30 degrees C. An important feature of the design is the flexible connection to the cold box which allows extensive freedom of motion; this freedom is ...

Light-weight flexible magnetic shields for large-aperture photomultiplier tubes [PDF]
Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2014 Thin flexible sheets of high-permeability FINEMET® foils encased in thin plastic layers have been used to shield various types of 20-cm-diameter photomultiplier tubes from ambient magnetic fields.

Review of Scientific Instruments, 1962
A liquid nitrogen refrigerator for a photomultiplier is described. This is of simple construction and involves direct immersion of the photomultiplier tube in the refrigerant. The inherent problems and advantages are discussed and a technique for preventing damage to the tube from thermal shock is described.
