Abstract
Nowadays, numerous fields such as High Energy Physics (HEP), medical imaging devices, portable radiation
detectors etc., require a robust, miniature, reliable and readily available photon detector that is stable in a
variety of environments, such as the presence of strong magnetic fields. The recently available 1mm2 active
area Multi-pixel Photon Counter (MPPC) sensors, produced by Hamamatsu Photonics, have been found to be
reliable and an attractive choice for the HEP applications.
The following sensor characteristics have been thoroughly tested by T2K collaboration: gain, dark noise, detec-
tion efficiency, reliability. These appear to be stable; in addition, the characteristic spread between numerous
devices was assessed. Sensors with larger area are being developed for imaging and direct-to-scintillator coupling
purposes
