COMMENTS

This has been a pretty calm and peaceful shift.We have had 7 full 1M event runs with a total charge accumulation of ~ 0.257C. A successful crossing of 400 spin flip counts during the shift.The target behaved as normally as it usually does.The detectors really worked hard during the whole night to refrain themselves from triggering any alarm.Now its time to sleep for us !!!
