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.

Tunnels closed today and tomorrow

- AE updates Vacuum and motion loop in the morning

- V. Bondar, J. Eidam and H. Sinn test vacuum in the afternoon (emphasis on understanding interlock conditions)

- A. Koch tests XTD2 imagers in the afternoon

Problems solved on Friday last week:

- Arms 2 & 4 of SRA are now moving. Apparently spindles had mechanical resistance that resulted in error condition. After moving a few times, this appears to be gone

- One of the problematic ion pumps had the serial line disabled. However, other lines 

 Tunnel closed today. Might re-open around 14:00

Note that that we re-convene briefly at 17:00 today in MCR (Mock-up Control Room)

Vacuum Loop:

Status:

• Large number of ion pumps not responding properly (2 in XTD2, 63 in XTD9). There is the suspicion that the parameters on some ion pump controllers might be set incorrectly, such as baud rate or the bus address. The generated error code indicates a bad address.
• Test in the lab requires Ion pump controller and PCL. No setup currently readily available. Check in the tunnel required. Could take place between 1200 and 1300 in XTD2 with a ZZ. (Update: B. Racky thinks she will be done around 1400 and would prefer access after this time)
• Preparations needed to include XGM 

EPS Loop:

Status:

• Temperature sensors return null value. Suspected firmware bug has been fixed and EPS loop updated by TF
• EPS to MPS interface requires testing. Should be done tomorrow

Motion Loop:

Status:

• Fixes have been applied to the MC2 lib. Tested for TECHNOSOFT driver. Should now work also for PBLMs . Tests do be done starting Wednesday

Imagers

Status:

• Camera driver for SR imager not working
• Camera driver for FEL driver working for imager in XTD2 but not for XTD9

Tasks for today:

• E. Eidam, V. Bondor, , J. Tolkiehn H. Sinn go through all ion pumps in the Silenzi list
• E. Eidam, T. Freyermuth check pump controller settings in the tunnel
• A. Koch and W. Ehsan work on Photonics Camera driver for FEL imager

Tasks for tomorrow:

• M. Planas, T. Maltezopoulos, N. Jardon, J. Eidam test XGM vacuum integration in XTD2 (not XTD9)

Email by M. Schlösser re alignment

Hi Tobias, hi Markus, Hi Winni,

Tobias, we discussed briefly the schedule for the T9 and T10 beamlines for the next few days, when we met in the tunnel yesterday.

From what i understand it is impossible to finish T10 until April 11th from the alignment and vacuum side. And probably more important, this also holds true for T9. There is at least one major problem with the alignment of the mirror chambers of T9 in XTD2, which will need some additional days to solve.
From my understanding at least the T9 beamline should be closed and aligned before putting SASE1 in operation. While it will of course be possible to send electrons down to the XSDU2 dump, it will not be possible to send photons to the experimental hall with the current state of the beamline.

Since it is not possible to work in XTD10 while the SASE1 electron beamline is in operation, i would propose to also finish this beamline before SASE1 electron startup. Since there is major work to do in XTD10 to finish the beamline, there is no hope to  do the remaining work during maintenance days. Finishing the beamline would require a major shutdown of the SASE1 branch later.

Since there will be no alternative to send the beam to (e.g. SASE2) for the next year (?), it does not make sense to stop work in XTD10 now, just to continue later then, without any overall benefit for the machine.

Of course i don't have a complete overview of all the machine schedule, but from my point of view it would make more sense to finish work in the northern branch, at least to align all components and to close the vacuum system, even if that means some more weeks before the SASE1 startup.

 Post on behalf of Raul Villanueva:

As we just finished the exhaustive testing and final adjustments of local
test and the interlock program for each of the turbopumps at each
Differential Pumping Sections in XTD2 Tunnel, we are happy to announce
that the system has been released and is up and running smoothly and under
control.  That means that the isolation gate valves in front of each
turbopump is open and therefore the latter is pumping already the beamline
as expected during the upcoming operation phase of the facility. That also
means that WP74, after having already received the wiring documentation
from the Vacuum Group can proceed with the same protocol to keep the whole
gas section in XTD2 in a consistent fail-safe status.

With this positive news, we wish you to have a nice evening,

Regards,

Raúl, Tobias and Nerea,

Table updated with status of SPB/SFX devices at end of XTD9 in preparation for SASE1 readiness meeting on 03.02.17

Dear all,

 the emergency power off test has been successfully performed in SPB.

Nobody can instantly cut the power to non hazardous racks (see racklist.xlsx managed by Ulf Brueggmann) by pushing the emergency off button anymore. The outlets in the experiment hutch do not go off. This is due to some missing cables. These will be installed in the next weeks and a new test will be planned for next shutdown.

Furthermore three racks for D.02 (SPB optics) and two racks for D.13 (SPB laser) cannot be powered off anymore by pushing the emergency off in D.09. The missing two emergency power off switching devices will be mounted in UV-XHEXP1-01-13-AV in the next shutdown. Until then the power to those five racks (D03-UH1 - D03-UH3, D13-UH1, D13-UH2) cannot be cut by emergency off buttons in D.02 or D.13.

SPB Loop 5 is back online:

- but without crate BKF00095-SPB_IRU_CHL (there is missmatch of hardware and documentation (investigation is ongoin)),

- pumps: PUMP_TURBO4, PUMP_TURBO5, PUMP_TURBO8, PUMP_ROOT_1, PUMP_ROOT_2 ,PUMP_ROOT_3 and IRU_VAC/PUMP_ROOT_1  are without serial connection

Interlock is inlcuded and ready for testing.

Best Regards,

Bernard

A pile up in the BrokerQueue was detected by CAS monitoring system and

a response action from the On-Call personnel was triggered.

Regrettably, the following device servers have been shutdown and will be re-instantiated.

- Dataloggers
- alarm server
- camera servers
- Motion Loop and Vacuum Loop beckhoff servers

Sorry for the inconvenience

This announcement is to notify you that the intervention planned to configure the interlocks as read-only will be carried out at 11:30.

A following message will notify of the end of the intervention

Alessandro

I will update the SASE3 MOV1 loop in 30 minutes. Please let me know if you would like me to postpone the update.

Best regards,

Marijan

changes according to the racklist on the electrical power distribution cabinets for rackrooms E.21 and E.22 are done. Power supply should be stable now. Please note that there will be emergency power off tests prior to the final acceptance test of SASE3 electrical installations around mid of May. You will be notified about the exact time and date.

The SASE1/SASE3 Readiness meeting next Monday is cancelled we will meet again on Wednesday the 3rd of October.

Correction: We will meet again on Wednesday the 4th of October.

Dear all,

the update to the SASE1 Timing system has been perform with no problems. The Timing board is now running firmware 1.24.0 and the doocs server was updated to version 7.8. I also updated the MCH firmware to version 2.19
 

The Motion loop in SASE1 is totally operated again.

Dear all,

we are experiencing constantly crashes with the photonic science camera in the SA1 imager FR. We found now out

- If the pixel format is set to Mono16 the camera will most likely crash, go in error.

- Before instantiation the camera may show Mono16. During connection Karabo but gets a fresh update and the field in the scene switches to Mono8.

Please don't apply Mono16 again.

Best wishes, Dennis
