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 
- activation measurement XS1 XTL/rear part by D3 
- Leak search and repair in the TLD beamline by MVS 
- A20 work by MHF-p (Exchange of filament heating, work on phase shifter) 
- CS8 RF  measurement on load (MHF-p) 
- Repair of wire scanner relais 
 
XTL: Access from Bahrenfeld 
- Exchange of filter in the BCM monitors by MKS 
- Repair of DCCT of a B2D quad 
- Change of AMC board in A8 by MSK 
 
XTD2: 
- ZZ for repair of a BPM system 
XTD10:  
ZZ for Photon Beamline Work 
 
 
All further work has to be agreed by the run or machine coordination.

 Hallo allerseits

Dear All,

During the afternoon CAS has a group activity. Any support can be requested via my phone number: 9-6776.

See you,

Sandor 

The vacuum loop is up and running again, with the version 1.11.4.

Denis Finze will connect the shutter signals of the XS3 shutter to the vacuum loop in rack 1.7.

AE on call service:

    Contact person:

        Nicola Coppola

WP74   OCD  for the  weekend 6.5.-7.5.2017:

Saturday: Jan, jan.gruenert@xfel.eu, 9-5777

Sunday: Theo, theophilos.maltezopoulos@xfel.eu, 9-6792

 Vacuum (M. Dommach):

• Systematic tests of ion pumps in XTD9 almost finished - ongoing
• Interface with MPS has to be tested
• Problem with the fast valve in XTD2 and 9 - it is possible to close it remotely but not possible to open it again. Checking of the cabling is ongoing by Vacuum group
• After restart of the vacuum loop many pumps in XTD 9 and 2 show an unknown error and some of them are not readble - CAS working on that.

PLC (P. Gessler, T. Freyermuth):

• Implementation of shutters in Karabo ongoing -XS3 shutter in the VAC loop now. XTD9 to do.

Karabo (A. Silenzi):

• GUI stability improved with a temporary solution. This should be enough to guarantee the proper functioning of images acquisition.
• Update of devices list ongoing
• Library for motors (base device), elmo and technosoft, being worked out.

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 - next meeting will be on Wednesday

Dear all,

I will make an update on the EPS loop, it will take only a moment.

Thank you

EPS loop in SASE1 is running again

Dear all,

The update of the Vacuum loop will take place in the next few minutes, later on, you would have access again to it.

Thank you.

Sorry for disturbing you, but I will have to wait till WP74 group finish a training in order to be able to put the XGM up again .

Vacuum is up and running again.

Thank you

CAS on call service for the night:

Gero Flucke: 9-8053

I will ramp down the system and bring it back up during the lunch break after installing the
tag 2.1.10.

To install a new version of Karabo use the script attached on your terminal

move your the karabo directory to a backup or remove it.

to backup:
$ mv ~/karabo ~/karabo.bkp
 

to remove:
$ rm -fr ~/karabo

then execute:
$ bash PATHTO/download.sh

 The system is up.

The users using virtual machines will encounter problems installing karabo 2.1.10 in the way that was described.
Further instructions will come later in the day

Dear all,

I will update the Motion loop to include the mc2 motors, it will be running again in few minutes.

Thank you!

 Dear all, 

contrary to the rumor that I spread last Tuesday in the PBS meeting, the magnet tests in XTD2/4 will be NOT done coming Monday and therefore the XTD10 will be be NOT open. It is still the plan to have one access day in XTD10 per week in the future (Monday or Wednesday to be clarified with the magnet group), but this will start only later this month.

Best regards

Harald 

Plan of WP74 OCD contacts for May.
Assignments are subject to change.

Initially availability is 10h-18h on the given days.
This might be adapted as well for later weeks.

 We are in the BRK and corrected the vacuum interlock condition.

We will restart the SA1 vacuum loop in a few minutes
