Formation of energy spectra of electrons in a dense weakly ionized plasma generated by fission fragments

Abstract

For a weakly ionized dense plasma irradiated by fission fragments, the coupled self-consistent Boltzmann equations for fission fragments and electrons are defined. The evolution of the energy spectra of fast particles in a plasma is investigated on the basis of these equations. Studies of the energy distribution function of fission fragments and primary electrons for a helium-3 plasma irradiated by neutron flux, as well as their non-stationary and stationary analytical solutions, are found and analysed.

I–V analysis for nuclear-excited low-temperature plasmas in porous metals

“…For the conditions under consideration (T e ∼ T a = 300 K, n a = 5 × 10 19 cm −3 ), k ic = (0.6-3.5) × 10 −31 cm 6 s −1 [4, chapter 4], and k dr,Ne + 2 = 1.8 × 10 −7 cm 3 s −1 [20], thus p a < 1 kW cm −3 for the n e = [a + 2 ] approximation is valid, which is satisfactory for even most pulsed nuclear reactor conditions. The solution to equation (9) is…”

“…Initial NLTP research pursuits beginning in the 1960s considered broad applications to direct energy conversion (DEC)-based nuclear power [3] and nuclear pumped lasers (NPLs) [4]; the only practical device that resulted was the ionization chamberbased neutron sensor-a crucial but rather niche use case [5,6]. By the 1990s, NLTP research was essentially abandoned (outside Russia) [7][8][9].…”
