NDOS CommissionMtng 20101206¶

Attendance: Jon, Sue, Jarek, Peter, Mark Messier, Minerba, Nate, Mat, Andrew, Peter, Alena, Kurt, Leon, Susan, Denis, Ryan, Xinjie, Ron, Rick, Greg

Agenda:

Andrew:
- Updates to the DCM kernel and DcmProgUtils broke the online software "test" release due to changes in "Set" and "Get" methods.
- Readbacks from FEB "work", but he is seeing non-sensical values
Peter: much effort is going on in understanding the trigger timing, which will likely consume the effort over the next couple of days:
- There appears to be an anomalous trigger offset
- We observe a 55 us jitter
- It would be good to add the Booster trigger into the readout (Holger responded that he would add this)
- It would be good to put a GPS+TDU on top of the MINOS building; unfortunately we don't have a spare TDU at the moment.
Sue:
- Mat & Denis were reporting difficulties getting runs started; mostly failing when (some) DCMs were configuring hardware.
- To improve the likelihood of a run actually starting, Sue changed the max. number of allowed attempts to configure the hardware on a DCM. That doesn't fix the underlying problem, but should help in the near term.
- More info is now being printed by the DCMApplication which should be useful for debgugging
- It appears that error bits are not clearing.
Jon: Kurt and Jon are working on getting the DCM hardware configuration into the database

Chad reported that he wired up the chiller on Friday and the data are being readout in Labview.
Plan is to work with Athans this week on getting the DCM DCS data readout
