Calculation of ρR-parameter and Energy Gain for Aneutronic Fusion in Degenerate P-~(11)B Plasma

摘要

Aneutronic fusion reactions are more safe and clean than the other reactions. One of the important candidate for these reactions is P-~(11)B. This reaction in characteristic conditions creates degenerate plasma. In a Fermi-degenerate plasma, the electronic stopping of a slow ion is smaller than given by the classical formula, because some transitions between the electron states are forbidden. The bremsstrahlung losses are then smaller, so that the nuclear burning of an aneutronic fuel is more efficient. Practical obstacles in this regime that must be overcome before net energy can be realized include the compression of the fuel to an ultra dense state and the creation of a hot spot. In this paper, ρR parameter (Lawson's criterion) and energy gain for P-~(11)B are given.
