XTD Tunnels open until 15:00. Later XTD2 and XTD4 are closed, XTD9/10 remain open

Vacuum Loop:

Status:

• One broken Beckhoff terminal was exchanged before the weekend. This was the first failure of this type in 2 years
• After this the system ran without hickup over the Easter weekend
• The fix applied for ion pumps that avoids triggering an interlock condition when there is a communication failure on the serial output should be also applied now to other vacuum device, e. g. the turbo pumps

EPS Loop:

Status:

• Requires an update to be done asap so that N. Gerassimova can continue tests with the PBLMs afterwards

Motion Loop:

Status:

• Movement of the PBLM motors (ELMO controller) is not satisfactory yet. Motors start and stop but the movement is uneven and stops not always requested
• There is no test set up in the lab. So tests have to be done in the tunnels (XTD9)

PBLMs:

• All systems in XTD2 were tested and cameras calibrated including some at the beginning of XTD9
• Work continues on remaining systems in XTD9
• System with motor movement is still unsatisfactory (see above)

Imagers

Status:

• 2 Imagers in XTD2 have no trigger signal. Suspicion is that this might be configuration problem. P. Gessler will investigate
• One pop-in (245) in XTD9 cannot be reached with IP. Suspicion is incorrect network configuration -> K. Fillipakopoulos

SPB Tunnel components

• Signal pins of the Attenuator crate were tested. DC voltage is seen there at different levels on different pins. This looks problematic -> P. Gessler

Karabo:

Status:

• Ran stably over the weekend 

Tasks for today:

Note: All loops should be left running and no changes to Karabo.

• Take equipment and junk out of tunnels
• Check trigger cabling for imagers in XTD2
• Check PBLM motor movement and continue testing in XTD9

Other topics

• Controlled access to tunnels is possible after 1500. Coordination with T. Haas and the DESY run coordination
