SASE1 Summary of Maintenance Period and Ramp up activities

Maintenance

- MC2 library update was deployed by EEE and most of the motors were tested afterwards
- Some motors were acting strangely: https://in.xfel.eu/elog/XRO+Beam+Commissioning/82
- As a rule, the Closed Loop and the Backlash Correction are atm incompatible and therefore you have to choose one of them. When a strong reproducibility is needed, the motor should remain in Open Loop and with Backlash Correction activated (2 microns for TY and 50 microns for TX, tipically): https://in.xfel.eu/elog/XRO+Beam+Commissioning/83|
- FXE mono1 bottom crystal was exchanged, realigned parallel to the beam. Recommissioning due WK5 together with FXE
- M1 and M2 chillers had service (water filling) and were then set on again before closing the tunnel. M3 is currently with cooling off.

Inst Dept Ramp up

- Several positions were fiducialised:
SPB alignment 2.41mrad 9keV
FXE alignment 2.4 mrad 9 keV
