Abstract

On the basis of 1-D coupled transport-hydrodynamic simulations from the stagnation phase, we investigate the ignition and burn dynamics of low temperature ignition D-T targets. It is shown that the ignition takes place in the central fuel region. The burn dynamics, however, differs from that of central spark ignition scheme because of the difference in density profile in the ignition phase. It is also shown by numerical simulations that the bremsstrahlung loss during the stagnation phase significantly affects the ignition condition and the energy gain.
