软X射线诊断冷却测试平台设计

软X射线物理诊断普遍应用于托卡马克聚变装置。在实验时,上限温度仅为75℃的软X射线诊断探测器将处于250℃的环境温度中,因此冷却系统不可或缺。本文分析了软X射线诊断探测器在运行时将受到的热负荷功率,并依据计算结果及实验时的冷却条件,创造性的设计了采用水、氦气混合制冷方式的冷却测试平台。所进行的测试结果表明,平台运行稳定,不仅能够很好的满足软X射线诊断的冷却需求,同时也为其它聚变诊断冷却系统的设计提供借鉴。

Design of Cooling Test Platform for Soft X-Ray Diagnosis System

Soft X-ray camera physical diagnosis is widely used in Tokamak.The upper temperature of Soft X -Ray detector is 75℃,while baking,the ambient temperature would reach 250℃which can easily break the de-tector.So the cooling system is indispensable.In this paper, the thermal load power of detectors is analyzed and a hybrid refrigeration test platform which combined water and helium is built innovatively based on calcula -tion results and cooling conditions.Experimental results show that the cooling platform runs stably,it not only meets the cooling demand of soft X -ray diagnosis,but also provides reference for other cooling system design of fusion diagnosis.
