光电倍增管（pmt）传统上是大型地下实验的一个组成部分，因为它们测量封闭检测介质中粒子相互作用的光发射。BUTTON实验将利用大约100个pmt来测量适合罕见事件搜索的不同媒体的反应。对低放射性10英寸Hamamatsu R7081 pmt进行了测试，表征并与制造认证进行了比较。本文描述了实验室测试和分析的增益，峰谷比和暗率的pmt，给电荷响应的理解，信噪比和暗噪声背景作为这些pmt的适用性接受测试水基探测器。在对这些测试进行评估之后，PMT的性能符合制造商的规格。这些结果对于探测器模拟中PMT响应的建模至关重要，并为设备在地下探测器中安装后的性能提供信心。
Photomultiplier tubes (PMTs) are traditionally an integral part of large underground experiments as they measure the light emission from particle interactions within the enclosed detection media. The BUTTON experiment will utilise around 100 PMTs to measure the response of different media suitable for rare event searches. A subset of low-radioactivity 10-inch Hamamatsu R7081 PMTs were tested, characterised, and compared to manufacture certification. This manuscript describes the laboratory tests and analysis of gain, peak-to-valley ratio and dark rate of the PMTs to give an understanding of the charge response, signal-to-noise ratio and dark noise background as an acceptance test of the suitability of these PMTs for water-based detectors. Following the evaluation of these tests, the PMT performance agreed with the manufacturer specifications. These results are imperative for modeling the PMT response in detector simulations and providing confidence in the performance of the devices once installed in the detector underground.
