Mitigation Strategies for Diagnostic Data Degradation due to High Neutron Yield of ICF Experiments at the NIF
Inertial Confinement Fusion experiments taking place at the National Ignition Facility are generating ever increasing amounts of fusion energy, with the Deuterium Tritium fusion neutron yield growing a hundredfold, over the past ten years.Strategies must be developed to mitigate this harsh environment's deleterious effects on the operation and the performance of the time-resolved X-ray imagers deployed in the NIF target bay to record the dynamics of the implosions.We review the evolution of these imagers in recent years and detail some of the past and present efforts undertaken to maintain or improve the quality of the experimental data collected on high neutron yield experiments.These include the use of a dump-and-read electronic backend, selection of photographic film with a low background sensitivity and optical filtering of Cherenkov radiation.
