Good news: The 'jitter'-tests was sucessful and BKR could identify the jitter source related to a wrong software setting around the AH1 module of injector.

This was now fixed and the jitter has disappeared  . It is likely that the tuning was compromised by this setting from the beginning of this run (July11).

On Monday morning, a fresh tuning round will be started with hopefully improved SASE performance. Until then photon delivery with what we have.
