Research Abstract

We have developed a new large area photodetector with concept of optical amplification. A photodetector based on this concept has advantage in its fast response and simplicity in the structure, which potentially provides a cost-effective ways to instrument large volumes with O(10^4-5) photodetectors in the next generation neutrino experiments. Some 8-inch prototype photodetectors have been produed and tested. Typical photo-gain factors of about 3 and time eolution of 1.1ns (FWHM) have been obtained.
