General

• From now on progress with the SASE3 tunnel will be monitored in this meeting

FXE (A. Galler)

• Work is going on to be ready for the start of instrument commissioning of Sunday
• Currently the LPD movement is being tested
• Today the firmware for the vacuum interlock system is being deployed

SPB (M. Messerschmidt)

• All inputs needed for the vacuum interlocks can now be read out
• Karabo was migrated to version 2.1.12. This appears to have some fixes for reading out cameras, but the GUI becomes unusable after ca. 10 min. Hence the version had to be rolled back to 2.1.11. This generated a lot of extra work
• The test of the emergency off system was done this week. In preparation the PLCs were shut down to avoid damage. Bringing the system back was a significant effort. This should be getting less as more and more parameters are migrated to the firmware
• A partial test of the MPOD power supplies was done in preparation for the AGIPD commissioning. Unfortunately some Wiener power supplies still have an older firmware that appears to produce voltage spikes when ramping up. This could damage the detector. Hence a firmware upgrade is needed. But no Windows PC was available on the controls network. The respective card was dismounted and taken to the lab for upgrading by K.-E. Ballack

Tunnel Installations SASE3 (M. Dommach)

• A lot of installation work was carried out during the service period last week
  • All Day 1 devices are in place
  • A lot of missing connections were made (water, pressurized air)
  • Calbing was done for the imagers
  • The Solid Attenuator was assembled
  • There are still two vacuum leaks, one of them is on top of the dump. This may have to wait for the next service period in August
• Focus during the next service period in August:
  • Install missing connection pieces and bellows in order to close the entire vacuum
  • Start bringing up Beckhoff loops with support from AE
  • Bring up as many components as possible 
• For the comments made by WP74/J. Grünert, see the respective log book entry today

Laser

• After a number of fixes and adjustments the AC parameters (Humidity/Temperature) are now according to specs

LPD

• LPD is now fully installed in FXE
• Work on the DAQ system starts next week
• Next step for AGIPD in HERA-S is to get the DAQ system working. After this the detector will be brought to SPB
• K. Wrona would like to cross check the configuration in HERA-S before this happens

AE

• Work focussed this week on getting the remaining SPB loops up, in particular loops 12 and 5
• For loop 12 a number of modules had to be taken out, modified and brought back. This relates to the operation of so-called SMARAGD motors
• Originally it was planned to test the vacuum interlock system in SPB first. This requires inter-loop communication and there are still unused loops in SPB
• Due to the problems with loop 12, it was decided to do the tests in FXE.
• The firmware for the FXE interlock should be deplyed today
• A meeting was held with MPS to clarify the interface between XFEL and MPS sind the MPS system cannot distinguish between the branch beam lines. This can now be handled by logic inside the PLC
• AE is preparing for the support of SASE3 during the next service period

CAS
