Neutron imaging design considerations for high yield shots

ORAL

Abstract

The neutron imaging lines of sight currently in place at the National Ignition Facility were all designed in the pre-ignition era. With shots now exceeding DT neutron yields of 1017 on a regular basis, the high flux and larger burn regions may necessitate new pinhole designs. This talk will focus on the framework of a new pinhole design model geared towards higher yield shots and the impacts of metrology errors on the interpretation of results.
