摘要

多阴极计数器的设计目的是通过检测计数器表面暗光子转换过程中金属阴极表面发出的单个电子，来寻找可能由暗光子组成的冷暗物质。计数器设计允许通过减去在阻挡电位配置中测量的计数率，从环境放射性和电子热发射中有效地区分背景。本文详细介绍了一种多阴极计数器的设计。

Construction of a Multicathode Counter for Dark Photon Search

A multicathode counter is designed to search for cold, dark matter, presumably composed of dark photons, by detecting single electrons emitted from the surface of the metal cathode of the counter during the conversion of dark photons on its surface. The counter design allows for the efficient discrimination of the background from an ambient radioactivity and the electron thermal emission by subtracting the count rate measured in the blocking potential configuration. The paper provides a detailed description of the design of a multicathode counter.
