The view flag was lost. So the vacuum was broken. During that time:
- the radiator was reinstalled so we have now both 10um and 25 um of Al radiator.
- radiator was recalibrated
- The collimation system and target was more precisely realign.
- The to left and right side 90 detectors was realign so now they are at the same level
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.
