Combination algorithms applied to source reconstruction for neutron coded images and restoration for incomplete coded images.

The neutron emission of compressed capsules filled with fuels in inertial confinement fusion implosions can be measured by neutron imaging systems. Source reconstruction is an important method in coded-aperture imaging. In this paper, we use a combination algorithm to reconstruct the neutron source image.

Design of the scintillator imaging lens for the neutron imaging system at the 100 kJ-level laser facility.

Deuterium-tritium neutron yield has reached up to about 10 at the 100 kJ-level laser facility, which makes measurement of neutron emission images possible with the neutron imaging system. There are two methods to collect neutron images from the scintillator array, optical fiber taper and the lens system. Here, we report a design of the lens system for the neutron imaging system at the 100 kJ-level laser facility.
