本文的目的是充分表征新的多阳极光电倍增管R11265-103-M64，由滨松生产。它的高有效有效面积（77%），它的像素大小，低暗信号率和检测单光子信号的能力，使这种管适用于高能物理的应用，如丰富的探测器。四管和两个不同的偏置分压器进行了测试。的增益和阳极的均匀性，暗信号率，串扰和作为温度的函数的设备的行为的标准表征的结果进行了研究。管的行为进行了研究，在纵向磁场高达100高斯。还研究了由高磁导率材料制成的屏蔽。研究了在强光下长时间工作对器件性能的影响。定量分析了增益和暗信号率随老化的变化。
The aim of this paper is to fully characterize the new multi-anode photomultiplier tube R11265-103-M64, produced by Hamamatsu. Its high effective active area (77%), its pixel size, the low dark signal rate and the capability to detect single photon signals make this tube suitable for an application in high energy physics, such as for RICH detectors. Four tubes and two different bias voltage dividers have been tested. The results of a standard characterization of the gain and the anode uniformity, the dark signal rate, the cross-talk and the device behaviour as a function of temperature have been studied. The behaviour of the tube is studied in a longitudinal magnetic field up to 100 Gauss. Shields made of a high permeability material are also investigated. The deterioration of the device performance due to long time operation at intense light exposure is studied. A quantitative analysis of the variation of the gain and the dark signals rate due to the aging is described.
