​FXE

• During the last users run there was a loss of optical laser. This was due to a mistake in CAS. Has been clarified already. It is pointed out by FXE that one should avoid  working on e.g. the control system during the users period. This is however, not always possible and a mitigation strategy is needed and requires discussions.
• Successful users shifts.

SQS

• Issues with motors have been fixed.
• Loop 3 will be probably updated today.
• In general several loops need to be updated, will be coordinated with SQS.
• SQS has the night shift today. Eventual tests have to be done today during the day.
• Motor valve can be implemented in the controls next week.
• Would be nice to have the GATT pressure in our DAQ system. CAS is looking into that.

​SCS

• KB coordinated motion has been improved

Another issue related to the non independency of interlocks between the SASEs: FXE waiting for pulse on demand. In the meanwhile in SASE3 the pressure in the GATT increases and the apertures go in to keep the pressure high. As designed, the interlock stopps the beam for 1 or 2 seconds, but also in SASE1. FXE loses the pulse on demand. 

It is clear that this is a complex environment and finding a solution requires time and the experts both on the desy side and XFEL side (e.g.AE, CAS) on the table.
