Page History

• Everyone was in the earlier DR so we recapped briefly and reached for questions.
• Looked through the review template slides.
  • Traci will upload all cost and schedule portions for everyone, but still review what's entered. 
• Laydown date is tbd, but most likely will occur Wed. October 4th. Ji is reaching out to schedule. 
• Alex and Barry have icalepcs conflicts for Dry Runs (10/9-10/13), so we will need to decide how to proceed with this conflict. 
• Plenaries will drive breakouts, but for the laydown, we can still start slides earlier.
• Breakout laydowns should have, at a minimum, the slides and a declarative sentence to describe what will be included. 
  
  • ~50%

Chris's Notes

advantages of daq:

• correlated (timestamped) data-taking across devices
  • will probably be done in MEC-U laser system
• (automated) live analysis
• data management (movement, archiving)
• MHz (10Hz MEC-U doesn't care)
• integration with elog
• handles larger data volumes

advantages of epics:

• simpler (fewer failure modes)
  • shared devices (daq/controls) don't exist: simpler
  • doesn't require timestamping
• more flexible (e.g. changing configurations)
• easier to have multiple people work in parallel

NOTE: current hutches (TMO/RIX) use epics-approach for laser system, but do send some timestamped data to hutch-daq (e.g. with a wave8 digitizer).  so something of a hybrid solution.

• LLNL's use of the DAQ will drive LLE. If LLNL system needs DAQ, then LLE will likely follow. 
• Alex wants to think more on if LLNL will need DAQ or if EPICS Achiever+ could be used. 

• Check in on laydown slides.
• Expectation to have slides created and at least some of the title slides inputted.  

-

• Continue DAQ discussions.
• If able, begin writing up some requirements on what the DAQ should provide to the laser systems.
