Dear all,

access to XTD9 has been extended until the Friday the 14.7. 14:00. Tunnel access schedule has been updated:

TAS

Dear all,

In order to finish the configuration of part of Hirex devices, we need to make an update of the Motion loop tomorrow morning at 10am. Please drive your devices to safe position before this hour.

Thank you

The encoder terminal in rack 1.5 has been replaced.

It will be replaced today around 1pm.Therefore Motion loop will be broken from this rack position.

We are finished. One encoder terminal has failed and needs replacing: rack 1.5 EC14

Dear all,

I have received a request from Konstantin Sukharnikov to break the Motion loop in XTD2 from Rack 1.5 in order to do checks in the CRLs. So you will loose communication with almost the whole Motion loop in SASE1. I will let you know when they are finished.

Thank you,

Dear all,

Today we are planning to integrate part of Hirex motors into the Motion loop of SASE1. Therefore, the loop will be break, so you will loose communication with whole XTD9 Motion part. I will back again to you when we are done,

Thank you

Here attached the main SASE1 panel

All control servers, brokers, dl and finally gateway were updated and restarted.

Dear all,

based on the information from todays BKR-meeting and communication with Harald Sinn, I updated the TAS: https://docs.xfel.eu/share/page/site/PSC/wiki-page?title=Tunnel_access_schedules

Basically, Harald is trying to keep XTD9 open until middle of next week, he still has to talk to DESY...

Cheers, Gerd

Dear all,

We will be working in the Motion loop till this afternoon. So as I said in the morning meeting, I will let you know when we have finished.

Thank you

General

• Accelerator was down all weekend due to cold compressors that were damaged in conjunction with the power outage on Friday
• Since 0700 all interlocks are broken and tunnels are open.
• Tunnels except XTD9 stay open until Thurday.
• XTD9 can remain open longer

Availability of Networks

• Network mainentenance that was requested last Friday for Tuesday has to happen today together with the rest of the facility. It was scheduled for 0700 - 0900 and is already almost done
• Following the network maintenance, N. Jardon will bring down the motion loop for KMONO integration. This only affects the tunnels and instruments can work during this time
• After the work by N. Jardon, IT needs to replace kernels on server machines. This will result in KARABO being down until early afternoon
• Afterwards CAS needs to bring back KARABO
• All measures will be announced on this log book

Instruments

• Implementation of vacuum interlock should be implemented this week. 
• SPB requires several adjacent loops to be included. Some of them are not up or complete. Maybe a simplified version should be installed first
• SPB requests loop 12 from AE. However this will take until mid July as it contains new motors (SMARAGD) that have not been tested so far

AE

• Work is currently ongoing on preparing to connect instrument interlocks to the DESY MPS system
• Work is also required to fix problems for the laser group that are most likely due to faulty wiring or a broken terminal

IT

• The dual power supply for switches saved a lot of work for IT after the power cut on Friday
• Unfortunately, the PLC CPUs in SASE1 are not on dual power. This should be upgraded as it is now also planned for SASE2/3.
• Dual power should also be put for the uTCA systems

The upgrade of the switches is finished to the extend that it allows Advanced Electronic group to work on KMono (Nerea is informed)

However, during the upgrade of the network one switch got stuck and this is the switch in XTD2 tunnel. The IP network in the XTD2 tunnel is not reachable at the moment (Beckhoff loops are fine) and we are going top the tunnel soon.

As discussed offline with NOC, Monday schedule was already fixed and not movable to Tuesday. Therefore, the network maintenance will take place on Monday 7:00 - 9:00.

During that time, no stable network is guaranteed.

After the network maintenance, the foreseen update and restart of all control server will take place, which take approx. ~2 hours. The exceptions are sase1 control servers and plc gateways as well as data logger and brokers and probably most importantly, exflgateway. These will be done after the work in sase1 (KMONO integration) is finished.  

Data Acquisition and Data Archiving

• K. Wrona summarised the basic ingredients of the system.
• All components are ready and tested individually
• Integration in the instrument environment is needed and will be done first in the context of commissioning LPD in FXE starting from 5 July
• DAQ and archiving for the tunnels was originally not foreseen but is being worked on now
• The split up of the KARABO environment into several "Topics"  was done on purpose to allow development with minimal interference
• The separate topics have to be re-integrated now
• The sildes from Krzysztof can be found here

XTDs

• KMONO integration should happen next week starting on Monday
• The planned work on the network switches should only start on Tuesday as it interferes with KMONO integration

FXE

• Topics to be worked on next:
  • Vacuum interlock integration
  • LPD integration
  • uTCA digitizer (was already working in Karabo 1.4.7)
  • Great Eyes Detector has a rate limitation that was not there before
• Longer term topics
  • Gotthard detector

SPB

• Loops 12 and 5 are prepared and uploaded but need to be commissioned now
• Firware for loop 13 is needed next
• Many motors seem to be getting 24V, but should be ruuning with 48V. What is wrong? This needs to be checked in the EPLAN and CRDs
• Loops appear to be missing components

Detectors

• LPD goes to FXE on 5 July. Integration work in the hutch starts immediately after
• AGIPD then goes into the X-Ray test stand in HERA-S
• Note that the DAQ infrastructure can only support one detector at full rate at a time. 
• In principle this should not be an issue at 30 bunches but it requires the veto system to work which needs testing

Electronics

• Work this week concentrated on preparing everying for deploying the instrument vacuum interlocks next week
• The problem with wrong names in the PP laser was identified as a wiring issue in one crate 
• Work also concentrates on timing and train builder to support detector integration from next week

Dear all,

according to Dirk Nölle access to XTD4 during the shutdown will be extended until Thursday.

Dear all,

I tried to update the TAS to include the times for each XTD during the shutdown-week at the beginning of July. It is currently not entirely clear when XTD9 and XTD10 will be searched, and as always this is subject to change...

General:

• ​Beam was brought to all SASE1 hutches on Friday. Beam was available to both instruments splitting it with M3 until Sunday morning. Afterwards SASE tuning was done and the beam should be back in the hutches some time today. Beam operation will continue this week with very low intensity. Split beam operation to both instruments.
• Rules as follows:
  • Only one bunch and very low intensity (< 100uJ)
  • Mechanical manipulation on vacuum parts only when shutter and all-metal gate valve are closed
  • Shutter and gate valve closed when instrument people are not in attendance
• CAS appears to be in a 2 day workshop from 9 - 5. This is a problem as some urgent work is needed. 

XTDs

• No access for KMONO commissioning this week
• All preparations that can be done for KMONO operation should be done however
• M. Messerschmitt prepares interface for the FEL imager to DOOCS so that KMONO can be used for tuning

SPB

• A list with essential components has been prepared
• It appears that some of the previously brought up loops contain only vacuum components. This should be fixed
• Loops 5 and 12 are needed most urgently now. 
• 5 additional servers are needed from CAS

FXE

• No remarks from FXE

It was just decided to put a very low intensity beam into the SASE1 hutches starting tomorrow morning at 8 AM. Both instruments declared that they are ready to accept it. Due to the very low intensity no special measures need to be taken outside the hutches. SRP and D3 shall be in the experiment hall. Harald Sinn shall coordinate beam activities from the BKR. Please note that the TC and S1R meetings take place as announced.
