杰斐逊实验室的GLUEX实验旨在研究9 GeV线性偏振光子束的光生反应。利用闪烁体描迹器和闪烁光纤阵列对射束光子的能量和到达时间进行了标记。光子通量使用对光谱仪确定，而光子束的线性偏振使用基于三重态光产生的偏振计确定。带电粒子轨道的相互作用，在中央目标进行了分析，在螺线管字段使用中央吸管漂移室和六个包的平面室阴极条和漂移线。电磁簇射在磁体内部的圆柱形蒸发纤维量热器和下游的铅玻璃阵列中重建。带电粒子的识别是通过测量线室中的能量损失和使用粒子在目标和磁体外的探测器之间的飞行时间来实现的。来自所有探测器的信号均通过闪存ADC和/或流水线TDC记录到存储器中，从而允许延迟3.3 μs的触发决策。探测器通常以40 kHz的触发速率和每秒600兆字节的数据速率工作。我们描述的光子束，GLUEX探测器组件，电子，数据采集和监测系统，并在第一个三年的操作实验的性能。
The GLUEX experiment at Jefferson Lab has been designed to study photoproduction reactions with a 9-GeV linearly polarized photon beam. The energy and arrival time of beam photons are tagged using a scintillator hodoscope and a scintillating fiber array. The photon flux is determined using a pair spectrometer, while the linear polarization of the photon beam is determined using a polarimeter based on triplet photoproduction. Charged-particle tracks from interactions in the central target are analyzed in a solenoidal field using a central straw-tube drift chamber and six packages of planar chambers with cathode strips and drift wires. Electromagnetic showers are reconstructed in a cylindrical scintillating fiber calorimeter inside the magnet and a lead-glass array downstream. Charged particle identification is achieved by measuring energy loss in the wire chambers and using the flight time of particles between the target and detectors outside the magnet. The signals from all detectors are recorded with flash ADCs and/or pipeline TDCs into memories allowing trigger decisions with a latency of 3.3 μs. The detector operates routinely at trigger rates of 40 kHz and data rates of 600 megabytes per second. We describe the photon beam, the GLUEX detector components, electronics, data-acquisition and monitoring systems, and the performance of the experiment during the first three years of operation.
