Title: Aperture design for the third neutron and first gamma-ray imaging systems for the National Ignition Facility

Abstract

The current construction of a new nuclear-imaging view at the National Ignition Facility will provide a third line of sight for hotspot and cold fuel imaging and the first dedicated line of sight for 4.4-MeV γ-ray imaging of the remaining carbon ablator. To minimize the effort required to hold and align apertures inside the vacuum chamber, the apertures for the two lines of sight will be contained in the same array. We discuss the system requirements for neutron and γ-ray imaging and the resulting aperture array design.
