Subignition fusion yields generated by fast heating of compressed deterium-tritium
Abstract
A simple model is used to calculate the fusion yields from the fast heating of compressed deuterium-tritium fuel. This model is in good agreement with detailed numerical simulations when the self heating of the fuel can be neglected and can thus be used to estimate the yields for near term fast ignition experiments where the deposited laser energies will be insufficient to cause ignition and propagating burn. The model is used to calculate the fusion yields as a function of the important parameters such as the fuel density, deposition energy, etc. It is found that the fusion yield approaches the deposited energy when more than 2 kJ is deposited into fuel with densities above 300 g/cc.
