为三角大学核实验室的恩格分极摄谱仪设计了一个焦平面探测器。探测器包由两个位置敏感的气体雪崩计数器：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，我们将详细介绍每一部分的建设沿着与他们的陪同电子和数据采集。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。的27 Al $（d，p）$反应的测量是用来证明检测器的性能，并说明能量校准的贝叶斯方法。
A focal-plane detector for the Enge split-pole spectrograph at the 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 27Al $(d,p)$ reaction is used to demonstrate a detector performance and to illustrate a Bayesian method of energy calibration.
