At 19:10 Frank called us that vacuum in sections 08 and 10 got worse by about 1.5 times. There is a possible danger that vacuum valves can get closed
if rest gas pressure is above the set treshhold.
Nikos warmed the cryostat by 0.5 degrees from 129.0 K to 129.5 K and the pressure became better than before. We cooled the system in steps of |
