Neutron penumbral aperture images of inertial confinement fusion targets achieve 60 {mu}m resolution (abstract)

Images formed by 14 MeV neutrons emitted from the core of inertial confinement fusion targets demonstrate 60 {mu}m resolution for the penumbral aperture imaging system used in our 1988 experiments. Hohlraums containing deuterium{endash}tritium filled capsules were irradiated at the Nova Laser Facility and produced images with detector limited resolution. Neutron yields ranged from 5{times}10{sup 10} to 2{times}10{sup 11}. The results imply that convolution of the aperture point spread function with the neutron emitting region of the target core is less than 40 {mu}m. Images produced by the indirect-drive hohlraum targets are compared with previously reported images of high-yield (1{times}10{sup 13}) exploding-pusher targets that show 150 {mu}m (full width half maximum) diameters for the emitting region.
