Found D2000 #1 activated and at 250C (25W) to prevent getting dirty when other NEGs are activated. See previous entries. Attempted activation of D2000 #2 using T 390C , rise time 30 m, hold time 90 m After 30 m temperature inside chamber increased by 5C. 390 C corresponds to 75 W. Attempted activation of D2000 #3 while #2 is holding temperature. Same parameters as above except T 400. After 30 min, temperature in chamber up by 10 more C to 110. Attempted activation of #4 as above. Set #2 then #3 then #4 to 250 C after hold time is over to protect them. All D2000 activated. Max temperature on Kapton bundle 110 C. Attempted activation of 2xUHV1400 linked to top C4, channel 2. No thermocouple available. Used power 200 W (2x100) rise time 30 m and hold time 90 min. Upon reaching 200 W no effect on chamber interior temperature. Increased to 300 W. Temperatures increased to 120C max roughly. Acceptable. Had to decrease hold time to 60 m to avoid remaining in cave alone for too long. Likely okay with 300 W (450 C?). Left on 150W (400C?) to protect from subsequent activations tomorrow. Because cables are unlabeled it's not clear how far the activated UHV1400 are from the detectors. If close, this recipe works. If far, we may have to use lower power for other modules.
