- X-ray pulse energy was relatively low in the beginning of the shift. It was partially recovered after running the launch optimization by BKR.

Continuous pointing drift in horizontal direction.

It may trigger a vacuum spike at SPB OH (MKB_PSLIT section) at 21:07 pm.

X-ray delivery

X-ray delivery
- 7.0 keV, up to 202 pulses at 564 kHz, 1.0 mJ.
- Average pulse energy was about 1.9 mJ on Tuesday and Wednesday. It has to be discussed with BKR tomorrow morning.

Optical laser delivery

Issues
- Pulse energy is very low as compared with Tuesday and Wednesday in this week.
- Damage found on IRU_SLIT4 Top and Bottom blades.
- NKB focus moved by ~20um at around 15:00 (during the handover period). SideMic X moved +20um to compensate it.

We had some trouble with the DAQ. It was not able to start runs properly.

We got the following error messages:

initially:

[00:01:27]: Problem of communication with data manager

[00:01:30]: Start new run ...

[00:01:38]: Failed starting data recording

DM: error at registerRun (Request to MDC timeouted)

after trying to start the run again:

[00:05:35]: Start new run ...

[00:05:35]: Failed starting data recording

DM: error at registerRun (Problem of communication with MDC

#Info: MDC-1100: MDC web server error: Error creating run

#Details: {'run_number': ['must be unique per proposal', 'has already been taken'], 'experiment_id': ['has already been taken']})

Cycling the DAQ resolved the issue.

Starting shift with mirror motor calibration:

- beam is centered on FEL imager

- pblm in XTD9 is inserted

We removed both silicon solid attenuator and pblm

Starting shift with mirror motor calibration:
