Neutron yield calculations from self-similar spherical compressions

The neutron yield from the compression-expansion cycle of a deuterium–tritium gas sphere is calculated using a self-similar hydrodynamic model.

Theory of homogeneous isentropic compression and its application to laser fusion

The hydrodynamic theory and properties of spherical homogeneous isentropic compression are discussed. Computer results are described showing that a close approximation to compressions of this type may be accomplished by light-induced pellet ablation if the light absorbed by the pellet is properly programmed with time, and is spatially uniform over the pellet surface. Pellet compressions in excess of ten thousand-fold are computed.
