Suprathermal-ion-driven fusion chain reactions in the pure deuterium system
Plasma Physics and Controlled Fusion(2024)
摘要
Abstract It is argued that fusion chain reactions in the D-D system is feasible with
supra-thermal deuterons in the MeV regime, with new generations of deuterons being
generated either via neutron-deuteron or proton-deuteron collisions. The propagation of
supra-thermal deuterons in an infinite, hot, dense deuterium target was studied using a
Monte Carlo method that includes multiple nuclear reactions, electron and ion stopping,
along with neutron and proton knock-ons. Over a wide range of densities we observed
significant, albeit sub-critical chain reactions in the multi-keV temperature regime. At very
high densities (over 1000 gcm −3 ) and temperatures (over 40keV) we observed chain reactions
that reached criticality. These results suggest that there is a case to re-assess the potential
of ICF based on deuterium-heavy targets.
