Attendance: Jon, Mat, Chad, Mark Mathis, Enrique, Athans, Philip, Peter, Minerba, Jarek, Chris, Zeb, Nick, Jan, Susan, Leon, Gavin, Martin

Agenda:

Peter: nothing major; there were a few updates that the DAQ group wanted to implement but haven't had time. Perhaps tomorrow (before noon).
Jon: no timing issues? Peter: everything looks fine lately.

Martin:
- smoke alarm was triggered during power outage, needs to be added to a checklist for when power outage occurs.
- scripts will now check to make sure crate is powered on. Also, scripts have been cleaned up.

Jon: spoke to Chuck Andrews; he will send Jon a brief summary of what was done on Tues. morning, but basically said that in general the grounding looked ok, although there is room for improvement.
Mat: went to NDSB and tried to recreate DAQ fallover by touching detector and shuffling things around. Tried removing e-box cover, no problem. Tried running shop-vac, no problem. Ran shop-vac + removed e-box cover, and the DAQ fell over. Peter restarted the DAQ but they were unable to reproduce the effect.
Jon will let Chuck Andrews know about these tests.
Power will be shut off again on Tues. morning
Leon: All 6 of full APD assemblies sent back had leaks, and they were able to identify where they are. Got some heatsinks from IU, and 90% of those were found to have leaks. Found leak location in 28/30 heatsinks. 99% of leaks come from TECC lead holes and wires. Will try to pot these.
Jon: requested Leon provide a list of
Martin: FEB card that was removed (with bad FEB temp. readout) is in the mail to Harvard
