摘要:

我们提出了一个原型的第一个跟踪探测器组成的250微米薄的光纤和硅光电倍增器(SiPM)阵列。该探测器采用模块化设计,每个模块由两个100微米薄碳纤维蒙皮之间的10 mm Rohacell泡沫机械支撑结构组成。支撑结构的顶部和底部都粘有五层增强纤维。具有250微米的通道间距的SiPM阵列被放置在光纤前面。我们展示了使用Bicron BCF-20和Kuraray SCSF-81 M型多包光纤的第一个模块原型的结果,这些光纤由FBK-irst/INFN Perugia的新型32通道SiPM阵列以及Hamamatsu生产的32通道SiPM阵列读出。空间分辨率为88微米± 6微米,平均探测光子数为10个/最小电离粒子。

英文摘要:

We present a prototype for the first tracking detector consisting of 250 micron thin scintillating fibers and silicon photomultiplier (SiPM) arrays. The detector has a modular design, each module consists of a mechanical support structure of 10mm Rohacell foam between two 100 micron thin carbon fiber skins. Five layers of scintillating fibers are glued to both top and bottom of the support structure. SiPM arrays with a channel pitch of 250 micron are placed in front of the fibers. We show the results of the first module prototype using multiclad fibers of types Bicron BCF-20 and Kuraray SCSF-81M that were read out by novel 32-channel SiPM arrays from FBK-irst/INFN Perugia as well as 32-channel SiPM arrays produced by Hamamatsu. A spatial resolution of 88 micron +/- 6 micron at an average yield of 10 detected photons per minimal ionizig particle has been achieved.
