After receiving beam from SPB, we noticed that there is a werid shape of beam in the FEL imager which was not observed yesterday.
Maybe someone left X-ray component in the beam. |

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. |

TUE 08:30AM:
The SA3 Cell 17 & 18 Phase shifters do not move and encoders are damaged. A ZZ is needed to exchange the encoders. Instruments are informed
and access will take place Tuesday morning. Machine has separated the north branch. |

04 Apr 2023, 07:44 we realize that the SetpointsHED Macro lost all values, probably during the Karabo Crash. Since it is a macro, the values arent stored
anywhere. DOC tries to recover. Meanwhile, we found the values for 3mrad, 2.5mrad and 2mrad in old screenshots and update the macro values from that. Saving
those now locally in nextcloud/user/Alex. |

Achievement
Measured tXAS at the Fe L-edge of Fe(bpy)3 using both delay and energy scans.
Issues
The cold traps ran empty on the chamber resulting in a pressure spike that interlocked the DSSC
The rough vacuum of the chem |

Achievements
Optimized BOZ for Co and Fe
Estabilished Stable liquid jet flow with 30 mM Fe(bpy)3
Problems
Jet froze several times
Chamber warmed up earlier in the day. This led to a "dusting" of CNCbl on many surfaces |

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. |

Machine RC Raimond informed PRC that there is an issue with the A4 module that needs to fix to have a continuous operation. To fix this they need
20 min.
Agreed with all instruments (SPB, SQS, and HED) that at 13:30hr machine will take over the beam for 20 min. |
