摘要

多光电倍增管（mPMT）光传感器将用于水切伦科夫测试实验（WCTE），以有效地检测整个探测器产生的光子。开发WCTE的目的之一是测试该技术，并在未来的水切伦科夫实验中实施，如Hyper-Kamiokande实验及其中间水切伦科夫探测器。每个mPMT是由19个3英寸的pmt组成的，它们排列在一个半球形的支撑矩阵上。本文描述了机械部件的设计和制造，在pmt和丙烯酸盖之间浇铸光学凝胶的过程，以及mpmt的整体组装过程。在mPMT模块中使用的电子器件的详细信息不包括在本文中，并将在单独的出版物中提出。我们还报告了对光学凝胶比的选择以及对铝反射器的透射率测量和反射率测量进行的研发。我们还介绍了使用405 nm LED对mPMT模块进行的光学测试，以及通过在pmt周围使用反射器来增加有效光敏面积的结果。本文还对WCTE的mpmt的生产和安装进行了总结。

Assembly, testing, and installation of mPMT photosensor for the Water Cherenkov Test Experiment

The multi-Photomultiplier Tube (mPMT) photosensors will be used in the Water Cherenkov Test Experiment (WCTE) to efficiently detect the photons produced in the whole detector. One of the aims behind the development of WCTE is to test the technology and implement it in future water Cherenkov experiments such as the Hyper-Kamiokande experiment and its Intermediate Water Cherenkov Detector. Each mPMT is built using nineteen 3-inch PMTs arranged on a semi-spherical support matrix. In this paper, we describe the design and manufacture of the mechanical components, the procedures for casting an optical gel between PMTs and acrylic cover, and the overall assembly procedure of the mPMTs. Details of the electronics used in the mPMT modules are not included in this paper and will be presented in a separate publication. We also report on the R&D performed on the selection of the optical gel ratio along with transmittance measurements and the reflectance measurements performed on the aluminium reflector. We also present the optical tests performed on the mPMT module using a 405 nm LED and the resulting increase in the effective photosensitive area by surrounding the PMTs with a reflector. A summary of the production and installation of the mPMTs for the WCTE is also presented in this paper.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
