The view flag was lost. So the vacuum was broken to fix it. During that time:
- the radiator was reinstalled and recallibrated so we have now both 10um and 25 um of Al radiator.
- The collimation system and target was more precisely realigned.
- The left and right side 90 detectors was realigned so now they are at the same level
- the measurements of upstream and downstream geometry was made.
Radiator calibration
From the top start to count. The 25 um Al radiator will come first after 28 CCW turns and 10 um Al radiator will come second after 67 CCW turns.
Upstream geometry measurements
