Machine went down overnight (4AM and 6AM) and could not be properly restarted by BKR.
Ongoing tuning is proceeding with RC onsite since 6AM; Instruments are informed and in direct contact to BKR.
Status 09:45AM: SA1 ~3mJ; SA2: ~500uJ; SA3 being restarted |

An XGM has two single-shot detectors, XGMD and HAMP.
The XTD2 XGMD amplifiers are damaged, thus I operate the XTD2 XGM with HAMP, which I usually use at > 18 keV.
In summary, the XTD2 XGM is fully operational, but I do not have a spare detector any more! Thus, a ZZ is organized for Monday 16.10. around |

End of Euler shift: all 3 SASE2 mirrors are now working with the Euler MDL.
We left the beamline aligned to HED, with M1,M2 on Pt for upcoming HED experiment at 18 keV.
Pre-absorber closed, CRL1 out, Solid attenuater with some diamonds. |

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) |

measured full temperature series on HGW during the day
problem with vacuum
in the cryostat-chamber, which triggered the interlocked during the data taking and blocked AGIPD for some temperatures

On multiple occasions this morning, the number of bunches was reduced to 1 without actions from our side.
Looking at the history of SA1_XTD2_BUNCHPATTERN/MDL/CONFIGURATOR, we noticed changes were applied by this device, presumably originating from
one of the watchdogs in SA1. This kind of silent changes is particularly inconvenient and could be easy to miss if one is not constantly monitoring that |
