Title: The effect of relativistic Compton scattering on thermonuclear burn of pure deuterium fuel

Abstract

The relativistic effects of the Compton scattering on the thermonuclear burn-up of pure deuterium fuel in non-equilibrium plasma have been studied by four temperature (4T) theory. In the limit of low electron temperatures and photon energies, the nonrelativistic Compton scattering is valid and a convenient approximation, but in the high energy exchange rates between electrons and photons, is seen to break down. The deficiencies of the nonrelativistic approximation can be overcome by using the relativistic correction in the photons kinetic equation. In this research, we have utilized the four temperature (4T) theory to calculate the critical burn-up parameter for pure deuterium fuel, while the Compton scattering is considered as a relativistic phenomenon. It was shown that the measured critical burn-up parameter in ignition with relativistic Compton scattering is smaller than that of the parameter in the ignition with the nonrelativistic Compton scattering.

  • An effect of nuclear elastic scattering (NES) on the energy transfer to plasma ions and electrons during (a) neutral beam injection (NBI) and (b) {alpha}-particle heating operations is examined on the basis of the Boltzmann-Fokker-Planck (BFP) equation for a beam ion and an {alpha}-particle in deuterium-tritium thermonuclear plasmas. The BFP calculations show that the enhancement in the fraction of the NBI heating power deposited to ions due to NES becomes appreciable when the beam energy is larger than 1 MeV. How the NES effect is influenced by the plasma condition is discussed.
  • One of the conditions for implementing high-efficiency thermonuclear burning in laser thermonuclear fusion is the formation of a thermonuclear burn wave in an inhomogeneous plasma. The authors obtain in the present paper, as a result of qualitative estimates and a direct numerical simulation of the dynamics of burn-wave formation, the conditions of the density distribution and the active-zone temperature at the instant of the maximum compression, whereby a self-sustaining thermonuclear burn wave is inevitably obtained in the target during the time of its expansion. 19 refs., 2 figs.
  • We derive expressions for the contribution from Compton scattering to the source term and the absorption coefficient for transverse waves, and discuss a number of simple solutions to the equation for the spectra intensity of transverse waves. We then discuss the effects of Compton scattering on plasma turbulent reactors, and find that under certain conditions the coupled equations for the radiation and particle spectra have power-law solutions, but that the particle spectrum decreases more rapidly with increasing energy than it does in the absence of Compton scattering. Numerical calculations of the spectral indices are give.
