We've cooled to base - but I'm not sure how cold…. Tower thermometer is reading > 200 mK, but I suspect it's reading incorrectly. In Run 73 it became clear that it was not really reflecting the detector temperature, and that the thermometer variations were larger than actual temperature variations. I had hoped that maybe the thermometer problems were due to He films and would go away, but maybe there's a more basic problem with the thermometer. In the current run the cold plate, still, and MC temperatures are pretty normal (Tower/MC/Coldplate = 225/31.8/192 mK, Still = 1.36 K).
