摘要:

下一代质子衰变和中微子实验,即超级神冈探测器之后的那些将在百万吨级水箱中进行的实验,将需要非常大的光电探测表面和大量的数据。即使使用大型半球形光电倍增管,预期的通道数量也应该达到数十万个。这里介绍了一个用于实施解决方案的资助研发计划。非常大的表面的光电探测分割在宏像素由16个半球形(12英寸)光电倍增管连接到一个自主的前端,其工作在一个无源数据采集模式。预期的数据传输速率是每根电缆5 Mb/s,这可以用现有技术实现。这种架构允许大大降低成本并促进工业化。本文档介绍了定义光电倍增管和电子器件要求的模拟和测量。一个原型的前端电子成功地测试了16个光电倍增管由一个单一的高电压供电,验证了内置的增益调节和校准原则。对光电倍增管玻璃的第一次测试和计算导致了对一种新的封装的研究,该封装针对10 bar的压力进行了优化,以维持高的水下压力。

英文摘要:

The next generation of proton decay and neutrino experiments, the post-SuperKamiokande detectors as those that will take place in megaton size water tanks, will require very large surfaces of photodetection and a large volume of data. Even with large hemispherical photomultiplier tubes, the expected number of channels should reach hundreds of thousands. A funded R&D program to implement a solution is presented here. The very large surface of photodetection is segmented in macro pixels made of 16 hemispherical (12 inches) photomultiplier tubes connected to an autonomous front-end which works on a triggerless data acquisition mode. The expected data transmission rate is 5 Mb/s per cable, which can be achieved with existing techniques. This architecture allows to reduce considerably the cost and facilitate the industrialization. This document presents the simulations and measurements which define the requirements for the photomultipliers and the electronics. A proto-type of front-end electronics was successfully tested with 16 photomultiplier tubes supplied by a single high voltage, validating the built-in gain adjustment and the calibration principle. The first tests and calculations on the photomultiplier glass led to the study of a new package optimized for a 10 bar pressure in order to sustain the high underwater pressure.
