Development of a new large area photodetector with optical amplification

我们研制了一种具有光学放大原理的新型大面积光电探测器。基于该概念的光电探测器具有响应速度快、结构简单等优点，有望为下一代中微子实验中大量使用O（10^4-5）光电探测器提供一种经济有效的方法。一些8英寸的光电探测器原型已经生产出来并进行了测试。得到了典型的光增益因子约为3，时间演化为1.1ns （FWHM）。

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.
