just FYI: current positions saved in files are x=1000 and y=-750. this information is good in case of crash.

We have mosty empty injections into CRYRING. Only sporadically the beam with good intensity is injected.

Michael Lestinsky is currently working on the problem.

A target temperature walkthrough has been initiated at 20:41 since the target density at S1 had slightly decreased (with ~0.1-0.2)

Current temprature 116K

set to 126K at 20:41

set to 95K at 20:47:30

set to 108.5K at 21:01:30, at this temperature was a sweetspot observerd for target density.

set to 109.7 at 21:08:30

set to 110K at 21:13:30 - we keep at this value for a while. the values at S1 are changing between 2.2-2.9e-8

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 0.1 degress down to 129.1 K and again observed the pressure rise.

We think we can stay with the present conditions. However, the pressure shall be monitored not to hit the treshhold.

07:00
Target density is hovering between 2.0e-8 and 2.3e-8
