Paper Abstract
A new neutron imager, known as Neutron Imaging System North Pole, will use an array of thick apertures to image the
neutrons produced in the burn region of imploding fusion capsules at the National Ignition Facility. While the resolution
requirements and parameters that drive the design of this array are similar to traditional x-ray pinhole arrays, neutrons
require thick apertures with narrow fields of view, and a precisely designed array of apertures is critical to allow
alignment and capture the required images with 10-μm resolution. This work describes the mechanical parameters and
limitations driving the design of the aperture array, in addition metrology and alignment requirements are discussed.
