Silicon-based Photo-Multiplier: a new generation of photon detector

Abstract: In the past few years, much progress was seen in the development of multi-pixel APDs operated in the Geiger mode (commonly known as "silicon PM" devices and have many different names). They have many advantages such as high gain, large photon detection efficiency, and insensitivity to magnetic fields and are expected to replace PMTs in some of applications. Multi-Pixel Photon Counter, produced by Hamamatsu Photonics, is one of variations of those devices. In this talk, I will first introduce the operation principle of multi-pixel Geiger mode APD. Then, I will present measurements of key parameters for the latest version of MPPC, and discuss future possibilities of improvements.
Speaker: Masashi Yokoyama - Kyoto University
Speaker Bio: Masashi Yokoyama is an assistant professor at Kyoto University in Japan, working for accelerator neutrino experiments. Before coming to Kyoto in 2003, he had been involved in the Belle experiment as a graduate student at the University of Tokyo. He worked with the silicon vertex detector and the observation of time-dependent CP asymmetry in the B meson system. Currently he is working for T2K neutrino oscillation experiment as the convener of the muon monitor group and co-convener of the near detector photo-sensor working group. He has also spent past year at Fermilab to lead the commissioning of SciBooNE neutrino scattering experiment.
