Achievements/Observations

Beam was focused on a YaG, alignment finished up to JF4M

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:

- found solid attenuator 0.5mm silicon inserted

- beam is centered on FEL imager

- pblm in XTD9 is inserted

We removed both silicon solid attenuator and pblm

Dear all,

we calibrated the mirror vertical motors to their geometrically neutral.

Please be aware that saved values for beamline settings may no longer be valid. This mainly applies to the vertical motor positions, but will have an impact on Tx and Ry values as well.

As starting point, use XRO Optics Setpoints 'C' - this setting was last used to bring beam to SPB
