Zwartbol %J Physics %D 2013 %I arXiv %X To provide a stable thermal environment for the AMS-Tracker, a thermal control system based on mechanically pumped CO2 two-phase loops was developed. It has been operating reliably in space since May 19, 2011. In this article, we summarize the design, construction, tests, and performance of the AMS-Tracker thermal control system (AMS-TTCS). %U http://arxiv.org/abs/1302.4294v1
