DAQ Update

Dave A discussed the current status of and recent project in the JLab DAQ group:

  • DAQ goup now fully staffed, recent hires Bryan Moffit and William Gu.
  • Have enough staff to meet 12 GeV obligations and deliver CODA 3 on time.
  • Bryan recently working on Linux ROC, William working on TI and TD boards.
  • CODA 2.6.1 release soon, COOL-based run control state machine.
    • uses latest cMsg and AFECS
  • Haven't started working on farm software yet.
  • Carl is working on fixing remaining cMsg VxWorks bugs.


Linux ROC

  • See Bryan's slides (link above) for more details;
  • Using the GE FANUC dual-core VME board.
  • Has 4 GB flash memory, Tempe chip (interface to VME).
  • Supports 2ESST.
  • Has longer interrupt latency and DMA setup than the Motorola PowerPC board, but this is not an issue.
  • Bryan had to modify the GE-supplied software to get better performance, including the Tempe libs.
  • The F1, FADC, and TI libs now work with the GE FANUC board.
  • Worked on scheduling, latencies, DMA speeds.
  • Improving core mgmt for threads gained 20 micro-sec.
  • Not using any version of real-time Linux, only real-time extensions.


ICALEPCS 2009

Elliott reported on the EPICS collaboration meeting and ICALEPCS 2009 conference held in Kobe, Japan. See his slides (link above) for details.


Coil Test

Elliott gave a brief update on the status of the coil test.

  • Steady progress in controls, but problems being found in the coils themselves.
  • Solenoid review coming up next week.
  • Should be able to use QWeak area nearby.
  • New tech hires helping a lot!
  • Most instrumentation ordered, a few items left.
  • Incorrect wire used for cryo sensors, must be replaced in all four coils.
  • Planning to work on three coils for other reasons so replacing wire not a problem.
