摘要:

T2K近距离探测器的量热计、距离探测器和有源目标元件依靠滨松光子多像素光子计数器(MPPC)来探测带电粒子产生的闪烁光。详细测量的MPPC增益,afterpulsing,串扰,暗噪声,和光子探测效率低光水平的报告。为了解释MPPC行为对T2K物理观测值的影响,基于这些测量开发了一个模拟程序。模拟被用来预测探测器的能量分辨率。

英文摘要:

The calorimeter, range detector and active target elements of the T2K near detectors rely on the Hamamatsu Photonics Multi-Pixel Photon Counters (MPPCs) to detect scintillation light produced by charged particles. Detailed measurements of the MPPC gain, afterpulsing, crosstalk, dark noise, and photon detection efficiency for low light levels are reported. In order to account for the impact of the MPPC behavior on T2K physics observables, a simulation program has been developed based on these measurements. The simulation is used to predict the energy resolution of the detector.
