Discussion items

TimeItemWhoNotes
Walk-in

Question about DR output and what engineers are doing

What is the time frame for projecting forward to cost savings? → 

Jama requirements exercise: will there be a review and release? → not a wholesale reset

Precluding of second petawatt: science cases / detail in CDR

  • Will review with UAP



Scope reduction conversations / workshopping
  • Workshopping to find every viable opportunity to cut costs
    • Clean areas out
    • Considering re-lowering TCX ceiling while expanding into TAO space
    • Questioning various zones in the experimental hall
  • Need further development of the operations model such that it can better inform decisions about needs for different facility elements



Laser systems considerations and changes

This was discussed last meeting. Just some additional opportunity (ROD 23)

Design is going to preclude the second petawatt as an upgrade option if DMPL is realized.


Measurement innovation workshop follow-ups
 		Categories 1 and 2 cost scales

UAP
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.

Science below objective KPPs (flagship implications)

Short pulse threshold 30J in 300 fs consider, say 50J at 200 fs: 3x less energy, 4x less intensity

  • Collisionless shocks
    • Any opportunity for new PIC simulations?


  • Ion stopping / heating expeirments
  • Assume 50 J 10 Hz shock driver for demixing experiment?

Long pulse threshold 100 J; say 500 J for sub-objective

  • Dynamic compression experiments at ~ 500 J
    • Inner mantle still accessible in principle

Experiments for project completion, day 1, year 2, and year 5 descriptions

Consider the example of MEC's commissioning / early science as a baseline. Eric M Galtier  or Bob Nagler can review.

  • notes that it was PRP driven from the outset.
  • Project and first experiments were almost simultaneous. Early commissioning / experiments were scheduled before end of project. Wasn't necessarily a great model. First experiment didn't have the short pulse in such that it could be timed (no working time tool).
  • Advantage of the approach is that it motivates an attempt to do real experiment and is a good shakedown.
  • Call for proposals timing - user experiments became commissioning.
    • KPPs of MEC: Was 25 J threshold; 55 was objective
  • Can find the PEP of MECi

Could also look to the XFEL example.
