CARME baking with heating tape continues
Left overnight at -
Ch1-3: 140 degrees
Ch5-6: 150 degrees
Ch8: 100 degrees
07:50 - Increased channels 1-3 to 150, channels 5 and 6 to 160, and channel 8 remain at 100. For the gas jet target, channel 2 increased to 150.
12:39 - Increased channels 5 and 6 to 170 C. All of CARME is >100 C except "Magnet Pipe" that is at 95 (probably OK given proximity to gate valve).
13:40 - Decreased channel 5 to 160 C. Bottom back of CARME was going up, but rest of chamber was not following along. Thermal gradients were getting excessive.
15:10 - Checked Kapton wire specs from Allectra. Max temperature of 311-KAPM-060 is 260 C in a vacuum not 160 C as erroneously remembered. Increased Ch 1 2 3 to 160 and channel 5 to 170. Planning on leaving until weekend.
Progress can be followed on
