摘要:

在FBK-irst研制了一个硅光电倍增器(SiPM)阵列,它有32个通道,尺寸为8.0 x 1.1 mm^2。每个250 um宽的通道被细分为5 x 22个矩形排列的像素。这些传感器被开发用于读出模块化高分辨率的光纤跟踪器。关键属性,如击穿电压,增益和光子探测效率(PDE)被发现是均匀的SiPM阵列的所有32个通道。如果噪声特性和PDE得到改善,这可以使具有SiPM阵列读出的光纤跟踪器成为可用跟踪器技术的有希望的替代方案。

英文摘要:

A silicon photomultiplier (SiPM) array has been developed at FBK-irst having 32 channels and a dimension of 8.0 x 1.1 mm^2. Each 250 um wide channel is subdivided into 5 x 22 rectangularly arranged pixels. These sensors are developed to read out a modular high resolution scintillating fiber tracker. Key properties like breakdown voltage, gain and photon detection efficiency (PDE) are found to be homogeneous over all 32 channels of an SiPM array. This could make scintillating fiber trackers with SiPM array readout a promising alternative to available tracker technologies, if noise properties and the PDE are improved.
