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 variety of environments, the presence strong magnetic fields. The recently $\sim$1mm$^{\textrm{2}}$ active area Multi-pixel Photon Counter (MPPC) sensors, produced by Hamamatsu Photonics, have been found to be an attractive choice for HEP applications. following sensor characteristics thoroughly tested T2K collaboration: gain, dark noise, detection efficiency, reliability. These appear stable; addition, characteristic spread between devices was assessed. Sensors with larger are being developed direct-to-scintillator coupling purposes.
