intense data taking on various samples
2 main issues:
- data collection using the optimize macro is too fast for the system and calibration and the data transfer from SDD to HDD is slower than collecting |

sucessfull data taking for user samples
beam loss for ~15 min and a small issue with scannerX of the FSSS (could be fixed without support) but otherwise smooth operation
contact with ITDM since the data collection speed could be too high for the transfer speed from SDD to HDD - should be kept under investigation.... |

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). |

15:15 SCS called and reported an issue with one of the motors of the SCS exit slit. DOC already looked at the problem and could not make the motor
move. XRO (Maurizio) is now informed and looks at the problem

Start up of HED ongoing for the three shifts
Day shift:
work on the new X-ray alignment scheme at 2, 2.5 and 3 mrad: test was positive and we can not work with Tx of M3 fixed at 4 mm for all |

We took the beam from 7 am, 24 h operation in three shifts.
We set up a new scheme for aligning the beam to the HED branch, which gives one X-ray axis downstream of the tunnel even if we operate at different
angles of M1 and M2 (i.e. 3 to 2 mrad). This relies on a fixed M3 Tx position and was tested for 2.5 mrad and 3 mrad during the shifts. CRL3 in the HED |

ZZ Access on 24th January (19:30h) - Replacement of Motor on SASE2 Undulator - Cell 17 Phase Shifter, posted by Raúl Villanueva-Guerrero on 25 Jan 2023, 08:44

Dear all,
last evening Suren Karabekyan and myself did a short notice ZZ access to XTD1. The reason is that machine operators detected the lack of response
on the Cell 17 Phase Shifter. The intervention was successful and around 20:30 we left the tunnel. |
