Beam drift in the horizontal direction (XTD9_XGM).
From ~16:00, X-ray beam started to drift in the horizontal direction. In total, ~0.3 mm drift observed within 2-3 hours.

achievements:
- finished SAXS data recording till 8am on time-resolved skyrmion nucleation and field dependence
- the setup is sensitive to beam transport drifts due to the closed hor-SLIT and the pinhole in FFT. were able to recover beam intensity by simple |

Achievements
Found RIXS signal from liquid jet
Measured static RIXS and PFY-XAS spectrum of Co(cp)(CO)2
Problems
hRIXS detector has a data latency issue and images were not being recorded in the DAQ. This required ~2-3 hours to solve plus time lost |

we change the DSSC timing to record the first pulse
sample was getting damaged with 26mJ/cm2 and scattering of the sample
was changed so we used lower fluence to observe t0 on the sample

Achievements:
measured the new sample, Silane, with different time delays
Problems
Tuning of SASE2 led to a 50% decrease in the SCS XGM intensity without affecting the SASE3 intensity. It also caused a jump in the BAM |
