  1. Are experiments in the correct regime? (pulse length, intensity, focal spot, preplasma profile, transport geometry) Is EP enough?
  2. Is the experimental evidence clear and how does it apply to ignition?
  3. What does that tell us-- the divergence would be in an integrated experiment (given constraints from point design as to geometry, prepulse, and implosion-caused distortion)?
  4. Do we have simulations that match experimental parameters, do they agree, and if so what does that tell us about the prospects for core-heating or ignition?

Moderators: Solodov and Strozzi

Do the simulations agree and can they predict electron divergence in ignition scale targets?

12:15 PM


1:30 - 4:00 PM

Short (<= 4 slides) presentations are allowed during the discussion

Moderators: Stephens and Honrubia


  1. What changes in planned capabilities are absolutely required for core heating? for ignition? Two omega? >10^20 W/cm^2? <40 micron spot size? >100 J ignition energy
  2. Is there a collimation strategy that a) can be implemented in target structure and b) will survive implosion and through the length of the ignition pulse? 3) What is the logical next step - on EP, on NIF. Must we directly characterize e-collimation or is core-heating from n signal sufficient diagnostic?
