| | DR Prep - Kickoff Slides | DR Kickoff Slides ; DR Agenda | - Everyone was in the earlier DR so we recapped briefly and reached for questions.
- Looked through the review template slides and schedule leading to the DR.
- Traci will upload all add 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- information. This should still be reviewed by presenters.
- 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 We agreed that laydowns should have, at a minimum, the slides slide tittles and a declarative sentence to describe what will be included.
- We will review laydown slides in our next two meetings before the Laydown scheduled Wed. Oct. 4th.
- Everyone, try and sit in on as many dry runs and lay downs as possible to get an idea on what's expected and learn from others.

| | Review of Laser System Risks added to Risk Board. | https://app.smartsheet.com/b/publish?EQBCT=173ec6bd4bb5413aa3cbb8ac687159f9 | This was addressed in an earlier meeting. We did not cover this topic. |
| | DAQ Discussions + IT Infrastructure Build for Laser Systems Requirements Sheet | IT Infrastructure Build Requirements Spreadsheet | 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. - DAQ does utilize LCLS-II timing which is the event timing system.
- 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.

| | Objectives |
|
|
| | - Check in on laydown slides.
- Expectation to have slides created and at least some of the title slides inputted.
| Presentation Folder: SC-3 Controls and Data Systems | - |
| | - Continue DAQ discussions.
- If able, begin writing up some requirements on what the DAQ should provide to the laser systems.
