Calculated neutron and proton yields for capsule shell thicknesses of 25, 35, 45, and .
Calculated peak proton energy (MeV) for capsule shell thicknesses of 25, 35, 45, and , viewed along or perpendicular to Hohlraum axis.
Experimental setup showing orientation of the Hohlraum with respect to the MIT wedge range filters used to measure the proton spectra.
Measured Hohlraum drive temperatures from Dante vs time. Dante measurement error is , which is indicated on the plot. Simulated Dante drive temperatures for full energy shots of 19.6 kJ are also indicated on the plot. Several shots plotted in the figure used reduced laser energy and have lower drive temperatures.
Measured neutron yields (total number into ) from shots with capsule shell thicknesses of 25, 35, 45, and . Measured neutron yields have an experimental measurement error of (indicated on plot). Calculated neutron yields are also indicated for each of the shell thicknesses.
Measured proton spectral downshifts (MeV) for capsule shell thicknesses of 25, 35, 45, and . Estimated measurement error in downshift is (indicated on plot). Calculated downshifts are also shown in each case. Calculations are also shown using an opacity multiplier of 2.0.
