This morning, SLinac heater margin floated in and out of alarm. As a cryo response, we received permission to change some clip heat values in 2L22, 2L25, and 2L26.

2L22-1 was raised from 11W to 19W, 2L22-6 was raised from 17W to 25W. Heater Readback is 0.5-0.6W

2L25-5 was lowered from 15W to 1W. Heater Readback is 1.06W

2L26-1 was lowered from 10W to 1W, 2L26-3 was lowered from 15W to 1W, 2L26-7 was lowered from 15W to 1W. Heater Readback is 3.12W

In total, electric heat use in the C100s was reduced by about 70W. This equates to ~2.8W/module of heater margin increase.
