<p>CARME baking with heating tape continues</p>
<p>Left overnight at -</p>
<p>Ch1-3: 140 degrees</p>
<p>Ch5-6: 150 degrees</p>
<p>Ch8: 100 degrees</p>
<p> </p>
<p>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.</p>
<p>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). </p>
<p>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.</p>
<p>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.</p>
