Experimental systems scope reduction considerations
ES scope reduction is tough because the overall budget is less than 10% of the project
Laser systems considerations and changes
(ROD 23)
Design is going to preclude the second petawatt as an upgrade option if DMPL is realized.
RRLP will not be precluded
Pointing stability: strictest test right now is based on hitting the target depicted in the first flagship. 20 µm cryo jet with a 5µm FWHM focal spot: Just hit the inner 10 µm of the target with the whole 5 µm.
The above description says a successful shot is at least at the 50% intensity point in the beam.
Likely this gets to about 10% with realistic design.
Noted that a good diagnostic analyzing in what way the spot is off alignment is important.
Want to answer: The flagship needs ____ shots in an experiment / run.
Given that we understand good vs bad shots a factor of 2 should not be a concern.
Session: presented MEC-U at the end. Seemed to go well. Comments had curiosity about kJ shot rate. Diagnostic development and challenges associated. What needs to be developed for AI feedback loops? ← putting it all together is the main challenge. There is work on this with LCLS, and we have the advantage of having the data handling capacity
UAP update
Rick Kraus, now at UNR, will be our new chair. Working next week to spin back up the UAP, including drop offs and new members.
