Shift summary 07.09.2023

Achievements:
1. found t0   on LSCO x=0.15 at pre-peak O K edge
2. fluence dependence at dt = 130fs, laser-on-off XAS => laser power at 50%
3. static XAS on the three samples x=0,.15, .4 aorund the pre-peak
4. setting for pump-probe: 1.1 MHz 520 pulses at 100% Transmission, PPL at 50%

Problems: 
10:10pm loss of optical sync on PP laser. realized before starting time-resolved experiments. coarse timing requried !

Program for the night shift:
reestablished timing
resume experimetns, i.e. time-resolved signal on sample (XAS) then start time-resolved RIXS.
