摘要:

在T2K近中微子探测器中,将使用约60 000个滨松多像素光子计数器(MPPC)。MPPC于2008年2月开始批量生产。为了进行质量保证和表征每个器件,我们开发了MPPC测试系统。对于每个MPPC,增益,击穿电压,噪声率,光检测效率,串扰和后脉冲率作为偏置电压和温度的函数进行测量。介绍了测试系统的设计和测量过程。

英文摘要:

In the T2K near neutrino detectors, about 60 000 Hamamatsu Multi-Pixel Photon Counters (MPPCs) will be used. The mass production of MPPC has started in February 2008.In order to perform quality assurance and to characterize each device, we have developed an MPPC test system. For each MPPC, gain, breakdown voltage, noise rate, photo detection efficiency, and cross-talk and after-pulse rate are measured as functions of the bias voltage and temperature. The design of the test system and the measurement procedure are described.
