The Pierre Auger Observatory is undergoing a major upgrade named AugerPrime with the primary aim to add sensitivity to the mass-composition discrimination of ultrahigh-energy cosmic rays. Two different photomultipliers will be added to each water-Cherenkov station of the surface detector of Observatory. To achieve the scientific goals of AugerPrime these photomultipliers have to ensure a linear response to input-light in a wide range. This paper describes a system developed for the validation of AugerPrime-photomultipliers.

验证光电倍增器以升级Pierre Auger天文台的设施。

皮埃尔·奥格天文台正在进行一次名为AugerPrime的重大升级，其主要目的是提高对超高能宇宙射线的质量成分识别的敏感性。天文台表面探测器的每个水切伦科夫站将添加两个不同的光电倍增器。为了实现AugerPrime的科学目标，这些光电倍增管必须确保在宽范围内对输入光具有线性响应。本文介绍了为验证AugerPrime-光电倍增管而开发的系统。
