General

• User operation starts on Thursday 14 September 08:00 in FXE
• Instruments alternate every 12h switching at 0800 and 2000
• A common SASE1 operations log book has been set up here. It is accessible for all inside XFEL
• The PIs of the first 6 user groups have been informed that the scope of their experiments will be rather "user-assisted commissioning". In compensation they will get more beam time in March 2018 if the objectives of their proposals could not be reached

SPB

• An effort was made with ACC to achieve good conditions for focussing. So far this has not been successful
• At 2200 on thursday these efforts were abandoned as there were no more ideas to try
• Also the power level in the beam was rather low
• Negative effects of running the detector on KARABO responsiveness are much reduced now
• This night KARABO froze up completely (no detector running) and no support from CAS was available (No response from calling the OCD mobile)

FXE

• Cross calibration effort for the beam energy was performed with HIREX. This succeeded after some efforts.
• The absolute energy scale could be established to within 70 eV. The fluctuations (averaged over several seconds) are around 20 eV
• Effort to synchronize the tangerine laser beam and to bring it to the sample continues. The quality of the sync signal is not very good. There are big signal losses in the fiber

Laser

• Still two problems with KARABO: Cannot reliably read date from wave guides and the python to doocs interfaces does not implement essential data types
• Currently working on aligning the NOPA
• The fact that the synch signal will not be available until end Sept puts a strain on the planned dates for beam delivery
• The full SYNC hutch will not be available until end Dec

Detectors

• The new GUI version gives good response while detector is running
• SPB was instructed on how to use the offline calibration
• LPD was brought into  the SASE1 broker topic
• Coolant leak in LPD was fixed but 1 super module had to be removed

Electronics

• A failsafe mechanism has been implemented in the firmware framework that allows the PLCs to continue running even if train ids should not be available from the timing system
• This requires an upgrade of all loops. 
• One encoder problem in SPB was identified as a problem with the cable
• One motor problem in SPB (injector y motion) is suspected to be a faulty terminal. The motor was moved to a test crate where it works fine. This can stay like this for the moment

CAS

• KARABO 2.1.16 was released. This release is not mandatory but recommended
• Work is ongoing on the DOOCS bridge
• XGM data is availalble now but requires a check by J. Grünert
• Work continues on the Gotthardt and GreatEyes detectors
• In the case of GreatEyes the vendor has been contacted and the reply is being awaited
• Good progress was made with data analysis on the ONDA cluster

ITDM

• Accounts for users are prepared. 
• Maxwell cluster is ready for offline analysis. Example files and programs are available
• Several PCs in XHQ have been set up that have direct access to the control network
• These PCs are only for monitoring experiment activities. They are not for general use and are not connected to the internet.
