Abstract:

This thesis examined the optimization of a Compton scatterer for use in simulating hard X-ray effects in the proposed Laboratory Microfusion Facility LMF. The LMF will produce inertial confinement fusion of deuterium-tritium pellets. The Compton scatterer is designed to reflect the X rays produced from the fusion toward a target. The scatterer should produce the maximum X-ray dose at the target while minimizing the neutron dose and gamma production. The scatterer must also control the dose rate by spreading the X-ray pulse to achieve a full width at half maximum on the order of 10s of ns. The current geometry includes a spherical Compton scatterer made of lithium hydride enriched to 95.6 Lithium 6. This work explored various parabolic scatterers using Monte Carlo transport calculations performed on the MCNP computer program from Los Alamos National Lab. The parabolic shape was optimized to increased the X-ray dose at a silicone target by a factor of 7. The geometry also decreased the neutron and gamma doses to less than 1 of the X-ray dose while achieving an 80 uniformity of dose across a 1-meter-radius silicon disk. Keywords Fortran.
