      I've always thought x-ray transparent plasma holds rad channel open, tweak spectrum... Just doesn't have enough pressure vs abltn

      @wellerstein Are both methods needed? Foam to slow ablation on outer-case while X-Rays ablates raw tamper? Control / focuses?

      if foam slows ablation on outer case, why would it not also do so on thermo fuel?

      as a point of differentiation between straight "radiation implosion" approaches.

      thinking foam could act like a radiation tamper. Stop rad from bursting case. But rad still hits raw secondary?

      like rad lens Slows ablation out but allows ablation inward secondary. Secondary carrot shaped uniform exposure?

      So while we enshrine the Mike/Bravo approach as the "gold standard" in Teller-Ulam design, it is not the only path.

          Teller always thought the cylinder was an "obvious" approach,
