Modern experiments in laser-driven inertial confinement fusion (ICF) are susceptible to contamination of the central hotspot by high-Z material during compression that impedes thermonuclear burn. Hotspot mix can be quantified using the ion temperature distribution of the implosion given the predicted deviation between the plasma and contaminant1. but current neutron time-of-flight (nToF) diagnosti...Show More
The Los Alamos National Laboratory Advanced Imaging team is currently in the process of designing a novel neutron imaging system for the National Ignition Facility (NIF). The team has been providing 2D neutron imaging of the burning fusion fuel at NIF for years, revealing possible multi-dimensional asymmetries in the fuel shape of the inertial confinement fusion reactions, and therefore calling fo...Show More
Summary form only given. The neutron imaging diagnostic has recently been commissioned at the National Ignition Facility. We will present the diagnostic performance characteristics, which have been measured with the collection of these first neutron images. The goal for this diagnostic is to collect two pinhole images at two different times. The long flight path results in a chromatic separation o...Show More
