1:30 PM Wed 18-Jan-2012 CC F326


Hovanes noted that everyone should contact Fernando if they need electronics boards or equipment, and contact Hovanes if they need VME CPU's. He asks that you contact them at least three months in advance.

Present: Elliott W, David L, Hovanes E, Beni Z, Somon T, Carl T, Mark I, Bryan M, Chris C, Dave A.

Software Review

The June software review will mainly be focused on the offline, but may cover some online topics. Stay tuned...

Counting House Installation

Hovanes and others reported that the UPS will arrive soon and installation is being scheduled, depends on when we officially get beneficial occupancy of the counting house. We likely will need a support frame under the UPS. About 19 racks are in the control room ready to be installed in the rack room. Power feeds are being designed. Networking, wireless and phones work in the office area, printer soon. Interim networking will be installed in the hall. We need to decide where we need clean vs UPS power.

12 GeV Project Lines

Elliott, David and Hovanes are working on completing the "Planning" lines in the 12GeV project schedule. Many documents are out or under review, most complete work on the corresponding line. The project ETC will be reviewed soon so the lines may change.

Configuration Database

David presented thoughts on the confDb first presented by Dmitry and Alex (see his slides for details) and notes that he is not in full agreement with everything they propose. They of course noted that this was a first attempt and are open to suggestions for improvement. Everyone agreed there should be minimal duplication of information between the configuration, conditions and calibration databases. Questions were raised concerning where base information is held for our board inventory: configDB, separate electronics inventory DB, IRMIS, whatever.

Dave also presented some prototype GUI's that access the configDB based on Python/GTK+/Glade. He reported that development was relatively easy once he got over the not-particularly-steep initial learning-curve barrier.

CODA Run Configs

Dave and Elliott proposed using SVN to archive CODA run configuration files. A CODA configuration is a set of files in a directory hierarchy so SVN is a natural choice. The SVN revision number tags the file set.

Electronic Logbook

Elliott reported this is on hold until Accelerator + four halls meet next month.


Dave A reported that CODA3 code is in an integration/testing stage now, prior to the alpha release in the next couple of weeks. The EVIOv4 preliminary version is out in C and Java, C++ not done yet. Glenn is trying to put together a single lab-wide single board computer purchasing plan.


Hovanes reported that the prototype driver for JLab discriminator readout is done, report is in the DocDB, along with another doc on Struck scaler readout (we purchased one board, driver only working on VxWorks at the moment). He is continuing to look at the EPICS alarm system "BEAST" from SNS. We are waiting on the meeting with Accelerator to learn more about archivers (i.e. DataBrowser/MyA integration).


  • Hovanes ordered an 8-axis motor controller for the soon-to-be-purchased Newport Goniometer. A visitor from Yerevan may work on this.
  • Elliott reported that the target date for cooling down the solenoid is still Nov-2012. Controls redesign waiting on George's FMEA (determine level of redundancy needed) and whether the NI PCX or CRIO fast/slow daq will work. The quench detector is understood and under control.

FDC Test

Beni needs three more TDC's, will contact Fernando.


Chris reported they are purchasing boards now and gearing up for full-crate testing.
