SCS Night Shift Summary
Achievements
Characterized optical laser spot at sample
Problems
FEL beam had very unstable intensity and spectrum. As a result no useful data could be collected during the night
FEL pointing seemed to be stable on all tunnel imagers. The issue was communicated to BKR, and they said that things looked fine from there perspective.
Large fluctuations in spectral distrubtion at SCS spectrometer were observed. See video at https://syncandshare.xfel.eu/index.php/s/emtwonCsQJJqpz6
Oth-order beam on SCS pop-in showed large intensity fluctuations with ~50% of the time showing no beam at all
