SPB/SFX

• CSS component commissioning. Concept and implementation finalized. EPLAN is being modified. PLC modification will follow.
• Loop 14 (Jungfrau) commissionig is ongoing. Issues concerning the simultaneous operation of more modules. SPB and DET on it. The detector is needed functional within 3 weeks.
• CRL implementation in the hutch will happen in April. AE and EET involved. ==> ZA needs the documentation of the CRL. before April. MS will ask the responsbile person in SPB.Ongoing.
• Changes concerning modules for the AGIPD motion are being discussed. Intervention on the modules planned for the next shutdown. AE, DET, CAS, SPB involved.
• Issue Basler camera <==> Loop. Will be solved offline with AE.
• Refurbished beamstop is needed by Mid. April. XRO has been informed.

FXE

SQS

• exhaust line for explosive gases has not been tested so far and no information is available to SQS. Urgent. SRP should comment.==> MMeyer is following up the issue. - NO update.

SCS

MID

• Issue with the remote control of the ion pumps. It is not possible to switch on and off the pumps remotely due to the fact that a wrong terminal was used . It seems this was also the same issue in SASE1 and 3. AE and EET are on it to fix it and update the doucumentation. ==> AE needs to perform a test at MID before deploying the solution. Since there are other priorities now the test has not happened yet. ==> Test has been shifted to HED. ==> Test will be synchronized with planned loop updates in MID. Will be coordinated between AE and MID.
• An automatic chain of communicaton is needed (TS?) to notify relevant peopole when the power is down. ==> UBr will follow up the automatic notification setup.==> Ongoing.  

HED

• Si bounce monochromators - Chiller leaks. Will be repaired in the next shutdown. ==> Waiting for delivery of parts. Not clear whether can be fixed in the next shutdown.
• hirex mono water connections will be reworked in March.
• Cables for the experiment hutch are being installed but some quality issues occured. Last pallets of cables have been sent back for proper confectioning. It is possible that there will be some delays. KA will discuss with LW how to prioritize cables to eventually minimize the impact on the commissioning.
• Si- mono commissioning ongoing
• CRL2 in XTD6 - issue wit motors losing steps. Being fixed
• DAQ and signal processing is neede int he OPT hutch. Ongoing with ITDM and CAS.

​OPT Lasers

• Modules for the time stamp have to be installed by AE. How long does it take? Will be discussed offiline with PG. ==> Installation dates: SASE1 in summer shutdown, SASE3 in the next 2 weeks, SASE3 being worked out.

​XRO

• In SASE3 additional safety shutters issue: Hardware will be ready by middle of Feb. On the 24 and 25. the installation and the modification of the EPS loop should take place if D3, SRP agree on the change request proposed by HS and MD. ==> Still no official decision from D3 and SRP. AE would like to get as many info as possible in advance to start preparing the loop update. According to MDommach NJardon is supposed to be already in the loop. ==> Concept in written has not yet been communicated to SRP and AE. ZA will talk to HS. ==> HW is installed. Loop update can happen monday or tuesday. The proposed additional radiation safety measures for SASE3 were discussed with Zunaira Ansari. A test is foreseen for 5 March. Implementation in the SEPS system will be directly coordinated between Zunaira and Nerea.

XPD

​VAC

DET

AE

• Correlation test between MCP detector and XGM last friday highlighted issues at the Karabo doocs interface concerning train id. Meeting AE, CAS, ITDM, XPD to follow up the issue.

​​ITDM

EET

​CAS

• Who is responsible for the bunch pattern recording for the different instruments? CAS will clarify with ITDM and AE.

SRP

• The self rescue training is supposed to become part of the access requirement in the DACHS system for the tunnel. This caused a lot of concerns during the meeting (visitors? Access to components only in the very firrt part of the tunnel ). PSPO will discuss with SRP .==> SRP is trying to find a way to minimize the impact of this training on the XFEL employees. Discussion with DESY needed.
