L1MU Status

L1MU triggers verified with detector hits

L1MU and L3MU tested L1MU triggers for 36x36

Testing of production power supplies (VICOR) in progress They work but 3.3V remote sense

does not work with programmable load

L1MU Card Status

But card testing (at AZ) is slow MTFB cards have numerous

shorted pins on their connectors that must be located and removed

Shorted pins also slow MTCxx testing

MCCM may need a production run but BU working hard to use preproduction cards

Shutdown Tasks

Install (hopefully) 6 central 05 (scintillator) octants 6 central 10 (wire) octants 2 north 05 octants 2 south 05 octants 1-4 MCEN octants

Update DPM control and L2/L3 message building logic

Complete no-L1CFT logic for above

Install production power supplies and gain final ORC

Complete cabling at detector front-ends

Complete cabling at L1MU trigger crates?
