摘要
文章从能量耗散、工作温度两个主要技术指标介绍了国外一些典型低温光子传感器;根据寿命、电能分配,质量和防振要求,提出在进行航天器低温系统设计时需要考虑的因素。文章还介绍了国外空间低温制冷机的发展状况、关键技术研究计划,以及进行空间探测的一些实验项目。
This paper introduces some typical cryogenic photon detectors,in terms of its power dissipation and operating temperature.During the design of spacecraft cryogenic system,some factors must be considered,including space cooler lifetime, power distribution,mass and vibration isolation requirements.The paper introduces the development of space cryogenic coolers abroad,including operational temperature,cold payload and effectiveness,and briefs their future development trend and the study plan of their key techn...
