Description
Silicon Photomultipliers (SiPMs) are semiconductor-based
photodetectors with performances similar to the traditional
Photomultiplier Tubes (PMT).
An increasing number of experiments dedicated to particle
detection in colliders, accelerators, astrophysics, neutrino and
rare-event physics, involving scintillators are using silicon Photo
multipliers as photodetectors.
They are gradually substituting PMTs in many applications, especially where
low voltages are required and high magnetic field is present.
Hamamatsu Photonics K.K. is one of leading
producers of photodetectors and is continously producing SiPMs
of improved performances.
In the last year Hamamatsu has introduced the 14160 series of
SiPMs with improved performances.
In the present work a characterization of these devices will be
presented in terms of breakdown voltages, gain, noise and pulse shape.
Particular attention will be devoted to the analysis of
parameters as function of temperature.
Finally a comparison with Hamamatsu SiPMs of the previous series
and with devices produced by other companies will be presented.
Summary
A characterization of the latest SiPM series from Hamamatsu.
