(a) Simulated 1D yield from radiation-hydrodynamic simulations vs amount of energy uniformly deposited at a linear rate for 3 ns from RT growth, cf. Eqs. (11a) and (11b), before deceleration onset in main fuel layer (blue) and outer half of main fuel layer (red) for adiabat-shaped 4-shock doped HDC capsule design;³⁴ (b) yield vs start time for (linearly ramped) energy deposition rate at 200 J total energy uniformly injected into main fuel. Energy deposition in simulations is a numerical surrogate for assumed preheat equivalence ΔQ of entropy of mixing TΔS.
