we were trying to make THz and cross correlate this to the pump laser.
We managed to see THz and an auto-correlation with the pump laser therein. Unfortunately we did not see any THz generation using the FEL.
Problems: |

9.752 keV, self-seeding, 700-800 uJ. Intensity is very stable, ponting is also much stable than usual. very good beam.
Beamtime #3326 - Axion search.
Successfully aligned two Ge crystals to Laue conditions (Rocking curve width ~0.002 deg) . Found Laue reflections after 2 crystals on Jungfrau |

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 |

18 Feb 2023, 23:37 Together with the last shift members, we continued shooting laser on Cu 25 um thick wire for another 2 hours. We got excellent quality
x-ray imaging with a series of time delay up to several ns (eLog ID 39). X-ray imaging is now commissioned. The magnification was x7.5.
19 Feb 2023, 01:30 We tried to go to x20, but we couldn't find the x-ray beam. We even put the burn paper in front of the Optique Peter to |

Ealier shift members managed to get a good quality image on Optique Peter by imaging the sample plane to the Optique Peter with downstream nanofocus
(CRL4b). The quality is far superiour compared to the one with upstream nanofocus, which does just a projection of sample (backlight). The decision is
to stay with the downstream CRL. They had a few full power shots. The problem of reading Zyla data when rotation = 0 is solved by Olly. He put the script |

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 |

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.... |
