摘要

15年后，第一艘使用直接辐射收集器(DRC)行波管的航天器已达到其任务寿命。本文利用数十个DRC行波管的在轨温度测量数据，回顾了DRC行波管在这段时间内热性能的趋势。结果提供了关于热环境和在恶劣热环境中遇到的绝对最高和最低温度的有价值的数据。

Radiation cooled TWTs at end-of-life: An evaluation of thermal evolution over 15 years

After 15 years, the first spacecraft using direct radiating collector (DRC) TWTs since their widespread introduction have reached the end of their mission life. This paper reviews the trends in DRC TWT thermal performance over that time, using on-orbit temperature measurements from dozens of DRC TWTs. The results yield valuable data about the thermal environment and absolute maximum and minimum temperatures encountered in the harsh thermal environment.
