More or less continuous beam delivery over the weekend
Beam was lost 2 times. Took almost 2h to recover in the second
case
The stability of the machine was poor.
SPB cannot achieve a good focus and FXE reports sync problems as the timining jumps |

User run is currently going well. Thanks to everybody!
Preparations need to be made for the October shutdown. Information
will be collected by PSPO and T. Tschentscher. Care must be taken that the relevant people are available. Priority will be given to XTD10!

First user experiments ended on Monday evening/Tuesday morning
They are considered a great success and overall the instruments
worked better than expected

A recent survey has shown that the experiment hall and the end of the tunnels XTD9 and XTDD10 have settled by as much as 6.5mm. If components
need to be re-aligned a completely new network of points would need to be established. This is not foreseen before the end of the year. A plot is attached |

Dear Tobias,
Just to clarify that the last information that we got from SPB was the message below. From this information and the technical evaluation that
we did the issue is not strong enough to classify Karabo 2.1.18 as "Currently it is not operational. An operational control system is needed soon". |

After discussion between XFEL Vacuum (J. Eidam) and DESY XFEL Run Coor (Matthias Scholz) it is agreed that XTD10 will only be closed
on Thursday and that XFEL will search the tunnel between 15:00 and 17:00. (This information became available only after the meeting)

The SASE3 tunnel XTD10 was searched by Janni and her team and interlocked about one hour ago.
It is now almost ready for first lasing in SASE3:
The vacuum is completely connected and closed from V0 all the way to the end

When PLC loops are restarted, still many device parameters are not properly recovered. This generates a lot of work
for the team. Recently an entire day was lost.

Recomissioning of the FEL has been bumpy and up to this point only very weak lasing could be achieved.
So far SPB had
only little beam and FXE had no beam at all. Both instruments state that the commissioning time for the up coming user run is insufficient
