摘要:

本文介绍了T2 K(Tokaito-Kamioka)长基线中微子振荡实验中μ子监测器的设计和性能。μ子监测器由两种类型的探测器阵列组成:电离室和硅PIN光电二极管。它测量在π介子衰变中产生的μ介子和中微子的强度和轮廓。测量对中微子束的强度和方向很敏感。检测器的线性度和稳定性在光束测试中被测量为分别在2.4%和1.5%以内。基于测试结果,μ子监测器测量束流方向的精度预计为0.25 mrad。

英文摘要:

This article describes the design and performance of the muon monitor for the T2K (Tokaito-Kamioka) long baseline neutrino oscillation experiment. The muon monitor consists of two types of detector arrays: ionization chambers and silicon PIN photodiodes. It measures the intensity and profile of muons produced, along with neutrinos, in the decay of pions. The measurement is sensitive to the intensity and direction of the neutrino beam. The linearity and stability of the detectors were measured in beam tests to be within 2.4% and 1.5%, respectively. Based on the test results, the precision of the beam direction measured by the muon monitor is expected to be 0.25 mrad.
