Bunch number control - SA3 FEL imager
As announced today in the XO meeting the SA3 FEL imager has a new feature, see screenshot, encircled:
- In case of danger for the YAG screen the bunches SA3 are set to "0" via the BunchPatternServer (SA3 Main scene). |

Trigger issue with SXP_XTD10_IMGES - Exit Slit imager
The external trigger of the Navitar camera was not set, fixed now.
The single pulse trigger of the imager: MCP + camera is tested and correctly working. |

YAG screen
The damaged screen "YAG2" with Al coating had marks and had been exchanged.
The Imager Watchdog now protects the screen - operational for some months i.e. the number of bunches is shut down to zero if the intensity at the |

Changed EPS Interlock condition for SPB_XTD9_IMGPI/SWITCH/SCREEN_OUT
SPB/SFX called DOC this morning for being limitied to two pulses by the EPS (Instrument should have called PRC instead)
After tracing the issue to the SPB_XTD9_IMGPI/SWITCH/SCREEN_OUT switch SPB/SFX decided to take this imager out of the interlock, confirming |

Day shift 28.02
Got the beam, aligned it up to the TCC, mirrors in 3 mrad configuration, checked positions for the CRLs. Optimised
beam at the HAPG. Beam stability was fine, energy up to 1,5 mJ at 8.2 keV, and up to 1 mJ at 9.1 keV (used for the spectrometer calibration). |

Morning - Users from proposal 3455 continued with their measurement program. Beam stable during the measurements.
Afternoon - Changed the setup from 3455 to 3326.
Evening - Beginning of the alignment for users. Beam stable. |

Morning shift:
- First thing in the morning ~7 am, the MDL in the SASE 2 topic were down. Even the watchdog which prevented us from moving SA2 attenuators.
DOC quickly resolved the issue (10 min). |

Morning shift:
- Tried to align the fiducial fiber in IC1 for the streak cameras, however it was unsuccessful.
- The karabo device for the SOP had to be restarted. Crosschecked that all the timings were still correct. |
