Subject: night shift summary 

achievements:

- measured delay scans at sample tilted by 20 degree

problems:

- we saw a drop in pulse energy around 00:30 in XGM at SCS, we verified that it was not because of the FEL not going through the HSLITS, in the end after calling BKR it was realized that there was indeed a problem with BC2, after fixing this, beam pointing was recovered and pulse energy as well

- beam pointing instabilities during tuning for SA1 around 6:30
