本文讨论了一种用于下一代中微子实验的大面积MCP-PMT的新设计。设计的主要动机是提高光电倍增管的量子效率（光检测效率）。在同一个玻壳内组装了两套小MCP单元，即前半球的透射式光阴极和后半球的反射式光阴极，形成近4 π的视角，提高了光电子探测效率。来自4 π光电阴极的光电子由两组MCP单元收集和放大。我们的目标是最终生产20台。直径PMT遵循这样的方法。我们将报告我们的ptoelectronic模拟和5英寸的结果的初步结果。直径原型PMT。最后对未来的计划和前景进行了讨论。(C)2011爱思唯尔有限公司版权所有。
This manuscript discusses a new design of large area MCP-PMT for the next generation neutrino experiments. The main motivation of the design is to improve the quantum efficiency (photo detection efficiency) of the PMT. Two sets of small MCP units, the transmission photocathode coated on the front hemisphere and the reflection photocathode coated on the rear hemisphere are assembled in the same glass envelope to form nearly 4 pi viewing angle to enhance the efficiency of the photoelectron detection. The photoelectrons from the 4 pi photocathode are collected and amplified by two sets of MCP units. Our goal is eventually to produce 20 in. diameter PMT following such an approach. We will report preliminary results of our ptoelectronic simulation and the results of a 5 in. diameter prototype PMT. Future plans and prospects are discussed at the end. (C) 2011 Elsevier B.V.
