Title: Argon X-ray line imaging - A compression diagnostic for inertial confinement fusion targets

Journal Article · · Energy Technol. Rev.; (United States)
OSTI ID:5258824

The paper describes argon X-ray line imaging which measures the compressed fuel volume directly by forming one-dimensional images of X-rays from argon gas seeded into the D-T fuel. The photon energies of the X-rays are recorded on the film of a diffraction-crystal spectrograph. Neutron activation, which detects activated nuclei produced by the interaction of 14-MeV neutrons with the selected materials of the target, allows to calculate the final compressed fuel density using a hydrodynamics simulation code and the knowledge of the total number of activated nuclei and the neutron yield. Argon X-ray appears to be a valid fuel-compression diagnostic for final fuel densities in the range of 10 to 50 times liquid D-T density.
