Aperture tolerances for neutron-imaging systems in inertial confinement fusion
2008
Review of Scientific Instruments
Design Considerations for Neutron Imaging for ICF Neutron-imaging (NI) systems use extended pinholes or penumbral apertures (with annular apertures as a particular case of the second) to generate images on the detector plane. 6 A full system consists of a neutron source, an aperture, an alignment system, and a neutron-sensitive detector ( Fig. 112.1) . When the neutrons pass from the source through the aperture, their spatial intensity at the detector plane is modulated according to the shape
