摘要

伽马射线能量跟踪阵列(GRETA)是一个完整的 4π 伽马射线跟踪探测器,能够在一个由高纯度锗晶体组成的紧凑球体内重建伽马射线相互作用的能量和三维位置。GRETA 探测器阵列球体可容纳 30 个锗四探测器模块(QDM)。在阵列正常运行时,这 30 个 QDM 将始终使用液氮(LN)冷却并保持在 100 K 以下,并且需要定期向每个模块上的液氮露天开关注入液氮。在探测器模块完全通电的情况下,液氮保温时间不少于 12 小时。每个 GRETA QDM 模块内共有 148 个前置放大器单元,由于每个前置放大器的功耗很高,因此需要对前置放大器舱进行主动冷却。此外,每个 Quad 模块上都有 4 个数字转换器模块,它们也会产生热量,需要冷却。闭环液体(乙二醇)冷却系统将提供所需的温度稳定性,并为电子设备散热。本文介绍了用于探测器的 GRETA LN 冷却系统和用于电子设备的闭环液体冷却系统的设计,包括技术要求、设计方案、关键部件、运行模式等。

Design of GRETA Cooling Systems
The Gamma-Ray Energy Tracking Array (GRETA) is a full 4π gamma-ray tracking detector capable of reconstructing the energy and three-dimensional position of gamma-ray interactions within a compact sphere of high-purity germanium crystals. The GRETA Detector Array Sphere will have the capacity to accommodate a total of 30 Germanium Quad Detector Modules (QDM). The 30 QDMs are to be cooled and maintained below 100 K using liquid nitrogen (LN) at all times while the array is in normal operation, and will require regular filling of a LN Dewar on each module. The Dewar is designed to allow the Quad Module to be operated in any orientation with a LN holding time of no less than 12 hours when the detector module is fully powered. An automated LN cooling and refilling system is required to supply LN to the 30 QDMs and ensure them maintained below 100 K. Each of the GRETA QDMs houses a total of 148 pre-amplifier units within the module, and with the high power consumption of each pre-amplifier, active cooling of the pre-amplifier compartment is required. Additionally, each Quad Module will have 4 digitizer modules attached to it, which generate heat and require cooling as well. A closed-loop liquid (Glycol) cooling system will provide the required temperature stability and dissipate power generated heat for electronics. This paper presents design of the GRETA LN cooling system for detectors and the closed-loop liquid cooling system for electronics including technical requirements, design schemes, key components, operation modes, and so on.
