The ignition and burn dynamics of low temperature ignition (LTI) targets are investigated by means of one dimensional (1-D) coupled transport-hydrodynamics simulations, in which the stagnation dynamics is appropriately taken into account. In this scheme, ignition takes place in the central region of the fuel and then the burn wave propagates outward owing to heating of the fusion products, without the production of a strong shock wave. The ignition condition in the LTI scheme is presented in terms of the usual ρR − T criterion and of the required implosion velocity. A scaling law for the limiting energy gain is proposed. It is shown that with enough fuel confinement (high ρR), higher energy gains can be achieved than those obtained in the previous model with volume ignited, uniformly compressed targets. (The limiting gain is about 1.5 times larger than that in the 'volume ignition' computations.) Without sufficient confinement, on the contrary, the bremsstrahlung loss during the stagnation phase increases rapidly, which significantly lowers the energy gain.

Correlation between ion/electron distribution functions and neutron production rate in spherical inertial electrostatic confinement plasmas

Correlation between ion/electron distribution functions and device performance, i.e. potential structure, density profile and neutron production rate, in spherical inertial electrostatic confinement plasmas is studied by solving the Poisson equation for various deuteron and electron distribution functions. For several combinations of the ion and electron convergences, dependence of the total neutron production rate on discharged current is discussed. It is shown that when electrons have high convergence and energetic component compared with ions, the neutron production rate can increase in proportion to more than a power of the discharged current, even if the neutron production is sustained mainly by the fusion reactions between the beam (deuteron) and background (deuterium) gases.

Effects of nuclear elastic scattering on energetic ion transport in hot dense plasmas

et al. 1990

Effects of nuclear elastic scattering (NES) on the transport of energetic ions in plasma spheres at densities and temperatures of interest for inertial confinement fusion are investigated on the basis of a linear Boltzmann-Fokker-Planck equation. After presenting the adopted calculational model, numerical results are given for two particular problems: (1) the deposition of 14.7 MeV proton energy in a typical deuterium sphere and (2) the inflight fusion probability for energetic deuterons in a D-T pellet. It is shown that in both cases NES effects are significant. An adequate treatment of the slowing-down process, especially consideration of the transport of NES recoils, is essential for an accurate estimation of the energy deposition and of the fusion probability. Calculations neglecting NES considerably underestimate these quantities.
