Dear all,

EPS loop is running with the latest hardware updates. Today, when I was trying to update the loop, I have found that someone has powered off the EPS crate in XTD2 Rack 1.5. Please, if you have to do some work in any part of SASE 1, let us know about it.

Thank you!

We have to disconnect the EPS crate in RACK 1.14 in order to check the interface to the MPS.

I will keep you updated

The EPS-loop is now complete again.

The interface from EPS to MPS is working now. One broken wire in the cable between EPS and MPS was found. We are using now other pairs for the signals "SA1_SYS_EPS2MPS/DCTRL/MODE1", "SA1_SYS_EPS2MPS/DCTRL/MODES" and "SA1_SYS_EPS2MPS/DCTRL/MODEM".

Cheers,

    Tobias

Since around 17h30 all XTD9 VAC loop is in error. It came back in karabo around 17h50. XTD2 not affected.

At that point, we had to reset every single karabo device of the XGM, then restart pumps etc.

Did the same also for the DPS upstream and downstream of XGM@XTD9.

XGM vatterfly valves will be opened by me only when I see that no further errors occur.

Currently, all but one pumps were restarted, also in Rauls DPS, only one of these not

No radiation measurements have taken place today (27.07) due to insufficent energy of the machine. We think we can achive the desired energy by tomorrow morning at which time the SRP group will attemtp to commission both the SPB OPT and SPB EXP hutch. The attached presentation shows the new expected time schedule.

A log book entry will be made when area restriction goes into affect and when it is lifted.

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

We will restart the SA1 vacuum loop in a few minutes

Since tomorrow there is no beam I want to use the time for some checks of the imagers in XTD2. Please, let the motion loop up if possible until 10 am, otherwise let me know.

• Power cut of the primary power line in the rackroom will occur to allow fixing of the emergency power off system (as agreed between TS ans MM last week). Happening today. After completion CAS and AE support is needed to switch the systems back on.
• AQS chamber is being removed
• New interlock definitions have to be tested and implemented asap. AE will discuss a date to SQS, although Friday might me a good time.
• SQS is eager to get the new trigger system from desy and AE and help testing it. It was noted that the trigger is linked to a specific SASE.

One word of clarification:

The discussion last Friday left some people uncertain over how to define stable operation and development periods. Hence I had a discussion with Nerea and Alessandro and agreed on the following:

PLC development: Tuesday - Thursday

Stable operation with Karabo: Friday - Monday

Handover period is Thursday afternoon between AE and CAS 

see you there 

Dear all,

This is a reminder to inform you that Readiness meeting will resume today at 13:00.

Best regards and Happy New Year !!

The migration has finished, to avoid temporary problem with ssh you can use

ssh exflgateway -o StrictHostKeyChecking=no

until it will be resolved in the morning ( the usual update of all hosts ssh keys).

Home folder has been changed to /data/<user_name> and it is slightly bigger then before...

Let me know if there is still anything missing.

best, Janusz

Hi everyone,

there was some miscommunication between us and DESY: only the Timing firmware and doocs server need to be updated, the RTM was already been replaced. This require update is similar to the one perform two weeks ago (see entry #449).

The time slot for this update is next Wednesday, 23rd January, between 16h and 17h. The update will affect all Timing Devices in SASE1. This operation should not take more than 10 minutes; during this time no timing signals will be generate (clocks/triggers/bunch patterns/etc.). Naturally, problems may occur during this update which will lead to increase down time.

If somebody sees a problem with the current schedule, please contact me.
