Characterization of the Hamamatsu 8" R5912-MOD Photomultiplier Tube

Tanner Kaptanoglu

摘要:

当前和未来的中微子和直接探测暗物质实验希望利用光子探测的改进技术。这些检测器中的许多是使用相对低成本、大面积和有效的光电倍增管(PMT)的大型单片光学检测器。一个候选PMT为未来的实验是一个新开发的原型滨松PMT,R5912-MOD。在本文中,我们描述了测量的单个光电子的时间和电荷响应的R5912-MOD,以及详细的一些直接比较类似的PMT。此外,进行光电阴极的1D扫描和脉冲后测量。这些测量大多是在三个R5912-MOD光电倍增管上进行的,其增益接近$1 \times 10^{7}$。测得渡越时间扩展($σ$)和电荷峰谷分别平均为680 ps和4.2。本文的结果表明,R5912-MOD在几个方面都是未来实验的优秀候选者,特别是由于其在时序上的窄分布。

英文摘要:

Current and future neutrino and direct detection dark matter experiments hope to take advantage of improving technologies in photon detection. Many of these detectors are large, monolithic optical detectors that use relatively low-cost, large-area, and efficient photomultiplier tubes (PMTs). A candidate PMT for future experiments is a newly developed prototype Hamamatsu PMT, the R5912-MOD. In this paper we describe measurements made of the single photoelectron time and charge response of the R5912-MOD, as well as detail some direct comparisons to similar PMTs. Additionally, a 1D scan of the photocathode and an after pulsing measurement were performed. Most of these measurements were performed on three R5912-MOD PMTs operating at gains close to $1 \times 10^{7}$. The transit time spread ($σ$) and the charge peak-to-valley were measured to be on average 680ps and 4.2 respectively. The results of this paper show the R5912-MOD is an excellent candidate for future experiments in several regards, particularly due to its narrow spread in timing.
