Abstract

The spectrum of neutrons released by an inertially confined fusion (ICF) plasma provides valuable information on the emitting plasma [1]. This includes, but is not limited to, ion temperature and confinement parameter rho*R. For instance, a neutron-averaged ion temperature is obtained from the width of unscattered portion of neutron spectra, T pronto sort(DeltaE_FWHM). As a first step in the development of a synthetic neutron diagnostics, we have included a neutron Monte Carlo package in the 2D ICF code DUED [6]. The source term accounts for both ion motion and bulk fluid motion. Scattering is also included, while, at the moment, secondary reactions and reactions by knocked-on nuclei are neglected.
