The XSDU2  area will be open (as XTD2) tomorrow between 9 ans 12. To register the access, please send also in this case a mail to T.Haas.

I added the requests that I was made aware of to the list of access requests for tomorrow. While the interlock in XTD2 will be broken and hence the tunnel is accessible without special procedures, please note the followoing

• Please make sure your request in in the DESY table of access requests 
• You have valid access permissions and two (!) dosimeters, one from XFEL one from DESY

Dear all,

I will do an update into the Motion loop. Would take only few minutes and the PLC will be running again.

Thank you and sorry

 XTDs Info:

Tunnel XTD2/4 will be accessible today until 1500. Dosimeter and General radiation training required. 

XTD10 will be closed starting this afternoon

Vacuum:

• DPS with interlocks was tested successfully yesterday evening but...
• ... Complete failure of gas sections in both XTD and XTD9 some time tonight. Valves were closed and turbo pumps were off. Reason is still being investigated
•  
• Systematic tests of ion pumps in XTD9 done for 3 vacuum sections. Currently only the pumps are tested. Tests of the interlock will follow
   

Karabo:

• The problem with the GUI server has unfortunately not re-occured. Hence it can currently not be debugged.
• Second GUI server is available for fall back
• Remote reset of TP controllers has been implemented and will be deployed in the next release

PLC

• A problem was found in the MC2 library affecting the ELMO controller.  This only affected the systems deployed in the tunnel. 
• The non-linear behaviour of the PBLM motors was reproduced independently of PLC and KARABO. Suggestion: Could this happen when the motor has to work against vacuum pressure? Evidence: It does not occur in the lab (no vacuum!)
• A video session with the manufacturer is schedule for next week to look at the problem

PBLM/Motion Loop: 

• There is a resource problem when trying to read out the cameras. This problem will be reconsidered once the general issue with the GUI server is solved.
• ASilenzi will discuss offilen with Natalia the acceptance test definition for PBLM
• List of errors and relative solution concerning ELMO absolute encoder implementation being worked out by AE/CAS

EPS

• Logic of EPS was agreed between AE and H. Sinn:
  • Currently only covers devices up to XS3
  • Vacuum ok requires all valves to be out of the way
  • Any screen down  forces single bunch mode
  • All imagers in safe position allows full beam mode
• Meeting next week @ DESY to discuss technical details with MPS group

SPB Tunnel components

• Renishaw encoder can be read out reliably after fix for error signal line
• SPB would like to work on the pulse picker next and is waiting for it to be integrated

FXE

• FXE guys would like to help with tests of Hard X-Ray Mono 

Tasks for today:

• Perform various maintenance tasks in XTD2, e. g. integrate CRLs, exchange photo tubes, exchange gases
• Investigate why gas sections switched off yesterday
• Continue test of vacuum components in XTD9

Dear all,
motion loop is up and all Karabo devices in it are running.

Thank you.

 Tunnel Status (T. Haas):

• Tunnels XTD2/4/10 were interlocked yesterday afternoon
• Beam is already going through the T2 and T4 beam lines to T4D
• XTD9 remains open until approximately 15 May

Vacuum (J. Eidam, R. Villanueva):

• The interlock in the gas section was tested successfully in XTD9. The interlock does currently not include the gas injection. This still needs setting up and testing
• Systematic testing of ion pumps and interlocks is ongoing in XTD9 but needs to continue next week
• The system generally works reliably
• However, there was an incident this week in which the gas sections in XTD2 and XTD9 went completely off. The reason is still not understood

Mirrors and PBLMs (H. Sinn):

• All three mirrors in the SASE1 beam line in XTD2/9 are installed and pumped
• N. Gerassimova installed PMTs in XTD2 yesterday and set up the cameras of the PBLMs
• The problem with injected properties disappearing was identified on the Karabo side and fixed. The fix still needs to be deployed
• The motors of the PBLMs are still not functioning completely. 
• The read out rate of the cameras is ok (of the order of 10Hz or better)

Imagers (A. Koch):

• Imagers in XTD2 and XTD9 are ready for beam
• Work continues on improvements
• Read out rate is ok, but the latency is sometimes high and needs to be unterstood

XGM (J. Grünert):

• The gas on the XGM in XTD2 was changed at the request of K. Tiedtke from Ar to Ne
• Tests were done with the remote control of the gas system. This is now fully functional
• The HV/Vacuum interlock is not operational yet
• Otherwise the XGM is ready accept beam. Next week software tests should be performed with the readout

FXE (A. Galler):

• Currently commissioning loop 1. There is still a problem reading out encoders. It appears that this is a firmware issue. TF is working on this.

SPB (B Weinhausen):

• Currently commissioning the SPB tunnel components. The encoders have the same problem as the one reported by FXE
• I broken terminal required changing

PLC (T. Freyermuth):

• CRL in XTD2 was integrated into the PLC motion loop yesterday during the access.
• A first version of the EPS logic was agreed upon and implemented. Details to be discussed again with DESY next week

Karabo (A. Silenzi):

• ITDM provided an additional control server
• A redeployment of Karabo is necessary and will be done later today (users will need to re-connect afterwards) 
• The problems previously observed with the GUI server have not re-occured. 

Plans for next week:

• Consolidate vacuum in XTD2 so that V0 can be reliably opened when first beam should be transported
• Finish work in XTD2, in particular PBLMs and instrument components
• Finish systematic tests of ion pumps in XTD2
• Deploy fix for Renishaw encoders in firmware

Other topics:

• We continue the 09:30 meetings next week until further notice

Note that plans for next week (points 2& 3) should refer to XTD9 and *NOT* XTD2

 Plans for next week:

• Consolidate vacuum in XTD2 so that V0 can be reliably opened when first beam should be transported
• Finish work in XTD9, in particular PBLMs and instrument components

 This Thursday the XTDs will be accessible with ZZ procedure. Access can be requested via T. Haas. 

Tunnel Status: XTD2/4/10 closed. XTD9 open. Controlled Access to 2/4/10 possible upon request

Vacuum (M. Dommach):

• Systematic tests of ion pumps in XTD9 concluded
• Tests of DPS in XTD9 should happen today with R. Villanueva
• Systematic tests of all interlock conditions in XTD9 should happen tomorrow

PBLMs (H. Sinn, P. Gessler):

• Debugging session for the ELMO controller was successful. The problem was traced to details in the parameter settings
• Proper setting of parameters is tricky and requires care and expert knowledge.
• Proper parameters now need to be programmed into the firmware. Manual setting is also possible but not favored.
• AE will set this up and deploy next week in order to maximise optimal use of resources (This week only one expert, TF, is here)

Imagers (A. Koch):

• Imagers in XTD2 and XTD9 are ready for beam
• It is important that images can be stored. This is not yet the case and will be required latest when PBS commissioning starts
• AK will be away from tomorrow until next Thursday

XGM (J. Grünert):

• Late yesterday, Karabo went into error triggering the interlock on the Vatterfly valves on both XGMs. Pressure is still low but slowly rising
• If the condition cannot be resolved remotely a local intervention is necessary. This can possibly wait until the scheduled interrupt tomorrow
• Today tests should occur with the DESY experts for gas injection
• Tests are currently hindered by the Karabo problem. AS suspects that this may have to do with the redeployment of Karabo yesterday. He is now working with high pressure on solving the problem

FXE (A. Galler):

• Currently commissioning loop 1. There is still a problem reading out encoders. It appears that this is a firmware issue. TF is working on this.

SPB (B Weinhausen):

• Fixes were deployed in the firmware for the Reinshaw encoder problem (16/32 bit issue). Still one encoder is in error. TF points out that this is a different problem. He will investigate

PLC (P. Gessler, T. Freyermuth):

• CRL in XTD2 was integrated into the PLC motion loop yesterday during the access.
• Meeting today with DESY experts to finalise the EPS logic
• Focus this week on SPB and AGIPD

Karabo (A. Silenzi):

• Karabo (Components Beckhoff-Device and Beckhoff-Com) were re-deployed yesterday.
• This maybe the origin of the problems observed in the evening 

Plans for today:

• XGM work on gas injection
• Bring back Karabo and clear XGM error codes
• Perform systematic test of DPS in XTD9

Other topics:

• No 09:30 meeting tomorrow due to access. 
• Request should be made to break the interlock in XTD10 on maintenance days in order to allow continuation of installation work

The GUI server has been redeployed and a second one has been added.

In order to access those:

please log out of the gateway and log in again using the usual command

ssh desyusername@exflgateway -L 44444:sa1-br-sys-con-gui1:44444

or

ssh desyusername@exflgateway -L 44444:sa1-br-sys-con-gui2:44444

Due the recent results from XFEL, the urgent maintenance is shiftet from Thursday 4th to Friday 
 5th. On Thursday, there will be operation till 14:00, after 14:00 the machine will be 
 switched to standby. All the work planned will shift accordingly by one day. No ZZ before 
 Thursday 14:00. 
 
The machine will be shut down Friday moring 7:00. 
 
Interlock situation: The machine will stay in interlock, only the access to XTL from OSDORF will 
 be brocken.  
 
XTL: Access from Osdorf
