DCS:¶

• Chad:
  • now writing env. data to the dB
  • will test more over the weekend, hope to have something to present at Monday's Comm. mtng.
• Athans: made some progress recently, hope to have a demo of the sender <-> receiver apps sometime next week

DAQ:¶

• Andrew:
  • we can read FEB status registers but:
  • have to switch to internal command mode to do that.
  • this switch disrupts data flow
  • requires a firmware fix, which is currently under testing.

• Peter:
  • latest version of DCMProgUtils is now being tested; it appears just one file is out of synch. The development release will be updated tomorrow
  • MB triggers:
    • still no clear signals being found
    • Holger's code is doing the correct trigger logic
    • events should be ~304 us after our T0.
    • the search continues...

• Mat:
  • new DSO data set collected yesterday, new hardware masks were generated; as a result, there was a net gain of ~500 channels.
  • some hardware work was done yesterday, where some APDs and optical connections were cleaned and I/V curves were taken. Details are in doc-dB 5492. Leon expressed concern about the procedure of the I/V curve data taking and warned of the potential of doing real damage to the APDs... the procedures will be worked out with Leon before any further data is collected.
  • Mat & Denis will remove ~10 more APDs from DCM09 (2-2).

• The Plan:
  • work on DCM software and firmware improvements will continue
  • DSO data will be collected every Mon., Wed. and Fri. mornings, before work begins on the detector. Jon will communicate this to personnel.

Shifters' report: nothing specific, all goes reasonably well.¶
