摘　　要：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。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.
