论文摘要
伽玛射线能量跟踪阵列(GRETA)是一个4-π检测器系统,目前正在开发中,能够确定在伽玛射线能跟踪梁阵列中所证明的锗晶体内部多种伽马射线相互作用(Gretina)中的多种伽马射线相互作用(Gretina)。电荷敏感放大器仪器使用模拟转换器将晶体及其输出转换为实时数字处理。在本文中,我们将介绍检测器系统和数据采集的设计。我们将描述用于以低速和高速率找到伽马射线的能量和时机的数字信号处理路径的实时组件。我们将描述数据采集系统硬件和固件的性能,并与要求进行比较。
The Gamma Ray Energy Tracking Array (GRETA) is a 4-π detector system, currently under development, capable of determining energy, timing and tracking of multiple gamma-ray interactions inside germanium crystals as demonstrated in the Gamma Ray Energy Tracking In-Beam Array (GRETINA). Charge sensitive amplifiers instrument the crystals and their outputs are converted using analog to digital converters for real-time digital processing. In this paper, we will present the design of the detector system and data acquisition. We will describe the real time components of the digital signal-processing path used to find the energy and timing of the gamma rays at low and high rates. We will describe the performance of the data acquisition system hardware and firmware and compare with the requirements.
