TUNL分极摄谱仪焦平面探测器组件
The Focal plane Detector Package on the TUNL Split-pole Spectrograph
摘要：
设计了三角大学核实验室恩格分极摄谱仪焦平面探测器。该探测器包由两个位置敏感气体雪崩计数器，气体比例能量损失部分，和剩余能量闪烁体。这种设置允许粒子识别和焦平面重建。在本文中，我们将详细介绍每个部分的结构以及相应的电子和数据采集。整个探测器的能量损失的影响，射线跟踪程序，和分辨率作为填充压力和偏置电压的函数也进行了研究。测量的$^{27}\!$铝$(d,p)$反应是用来证明检测器的性能，并说明贝叶斯方法的能量校准。
英文摘要：
A focal plane detector for the Enge Split-pole Spectrograph at Triangle Universities Nuclear Laboratory has been designed. The detector package consists of two position sensitive gas avalanche counters, a gas proportionality energy loss section, and a residual energy scintillator. This setup allows both particle identification and focal plane reconstruction. In this paper we will detail the construction of each section along with their accompanying electronics and data acquisition. Effects of energy loss throughout the detector, ray tracing procedures, and resolution as a function of fill pressure and bias voltage are also investigated. A measurement of the $^{27}\!$Al$(d,p)$ reaction is used to demonstrate detector performance and to illustrate a Bayesian method of energy calibration.
