Abstract :
The Multi Pixel Photon Counter is a novel semiconductor photon sensor which consists of 100–1600 micro APD pixels. Each pixel works in limited Geiger mode with an inverse bias voltage around 80 V. The MPPC has many remarkable features such as high gain, large photon detection efficiency, low cost and tolerance for magnetic field. Fundamental properties, such as the gain, dark noise rate and inter-pixel cross-talk, have been measured with three different samples which have 100, 400, and 1600 pixels. Variation of the gain over 750 samples, and uniformity of the gain and photon sensitivity within one pixel are also evaluated. As the result of the tests, it is confirmed that the MPPC has satisfactory performance for many applications, not only for high energy physics experiments but also for medical engineering systems.
