shift summary EulerMDL calibration, posted by Antje Trapp on 16 Apr 2023, 23:06 11x
|
First four pictures: beam line status at beginning of shift - Beam aligned to MID
Idea is to check M2 parasitic motions again on M3 popin. therefore bringing M2 close to 0 with all vertical motors and Tx as much as possible
without using beam on the popin. |

ALL RY MOTORS ARE IN MICROMETER SCALING, posted by Antje Trapp on 19 Jul 2023, 12:34
|
This has several implications:
- ALL PREVIOUSLY SAVED RY POSITIONS ARE OBSOLETE!
- Ry values seem to have changed by a factor of 1000 |

Shift summary of SASE2 alignment, posted by Antje Trapp on 20 Jul 2023, 18:20
|
Mirror pitch motors Ry were tested after scaling was changed to um.
Tx and Ry motor positions were calibrated to their measured physical positions.
ALL PREVIOUSLY SAVED SETTINGS FOR SASE2 MIRRORS ARE OBSOLETE! |

Beam aligned to HED, posted by Antje Trapp on 21 Jul 2023, 16:54

M3 vertical motors calibration - EulerMDL, posted by Antje Trapp on 02 Oct 2023, 21:48
|
Second iteration and sanitty test for vertical mirror motion (Y) and vertical beam alignment (ROLL)
Vertical motors were calibrated and offsets saved in Euler MDL (no calibration of motors done so far - this should be performed during ramp up
after WMP) |

Euler calibration and Mirror setpoints, posted by Antje Trapp on 03 Oct 2023, 22:51
|
euler MDL was calibrated for all three mirrors.
Optics setpoints saved in XRO setpoints for MID and HED

Euler MDL bugfix - motor velocities restored after stop, posted by Antje Trapp on 10 Nov 2023, 14:10
|
The Euler MDL was updated, so that velocities are restored to standard values also after the stop button was hit before motion was finished.
Please be aware that due to the synchronized motion, which is neccessary to keep the beam on the screen, some motors may move for a longer time
with very slow speed (main reason - backlash compensation). We are working on a solution with a minimum speed. |

scanning for HED beam, posted by Antje Trapp on 24 Jan 2024, 14:00
|
We found reflection of M3 on M2 popin, but could not locate the beam on HED PBLM nor HED_XTD6_SDLBM-1
scanning both horizontally and vertically around previously saved positions on M3 popin.
managed to get beam through to sdlbm-1. No beam found downstream of that. |

It was possible to align to HED in parasitic mode to seeding tests
mirror horizontal position (coating stripes) was optimized as far as possible under parasitic conditions
vertical motors calibration and EulerMDL calibration still to be done - collimated beam needed for that. |

Vertical motors of M3 now calibrated in first iteration and gemetrical neutral calibrated to 0 in motor settings!!!
New HED positions saved in XRO setpoints 'C'
euler calibration not completed for M3 |

Solid attenuator arm 5 limit switch, posted by Antje Trapp on 30 Jul 2024, 10:38 6x
|
On 27th of July, it was reported that arm 5 of the solid attenuator did not stay in 'out' position when retracted, but moved
in immediately again.
Reason was, that the limit switch for the 'out'-position did not trigger, and thus the actuator was in error state. Default for error |

Issue, posted by Angel Rodriguez Fernandez on 28 Mar 2023, 15:26
|
The door from MID side entrance was smashed and we lost the radiation permit.
The acciedent happened between 11 (when the door was lest use by MID members) and 14:19 (when the picture was taken).
It is possible that we will have the permit in the next hours to countinue. |

stable SASE beam delivery with 1mJ pulse energy
we took data for different optical laser excitation fluences and delays
we
changed from the optical lock to the electronic lock to measure also longer delays.
