global trigger timing change (Fred)

Sequencers etc. are ready for the global timing change. We will need new AFE firmware to adjust the VSVX pipeline; this needs some more testing, but does not stand in the way of the global timing adjustment. Ron reported that the Framework adjustment is tentatively scheduled for next week.

hardware; power supplies (Jamieson)

Two power supplies are at Vicor for upgrading, and eventual DFEA 3.3 V power replacement. Transition board rebuild (longterm G-link fix): Design review has happened, the art work is done, most parts have arrived at Fermilab. The board order is being pushed through the system.

CTT integration (Levan, Ricardo)

The L1CTT chain debugging is once again underway at the combined test stand, after observation of some puzzeling behaviour on the platfrom. On the positive side, we are seeing the right number of Neoterms arriving at the Trigger Framework, and those Neoterms disappear when the DFEAs are switched to send null events.

Our MTM input timing can be inspected in MCH3 on one of the Muon debug cables (#48). The sync gap/first crossing signal is absent most of the time, and 10 microseconds off with respect to a Muon signal when it's there. It is also the wrong length (2.04 instead of 2.244 microsecond).

Test vectors in the CTOC need further CTS debugging.

The platform CTTT has been replaced.

The FPD would like to borrow a 2x1000 board; this can be arranged as soon as we don't need the board anymore at the CTS, and as long as it's understood that we would treat it as a 'hot spare' for the CTT.

L2: Jamieson

Jamieson will need a couple of weeks to finish the L2 firmware for the DFEA.
