Reaction-network modeling of doped fusion plasmas

Develop a self-consistent reaction-network treatment of light-nucleus-doped hydrogen plasmas that includes evolving fuel composition, secondary burn fractions, radiative feedback, and the resulting burn dynamics and power balance.

Background

The paper considers doping hydrogen plasmas with species such as 3{}^{3}He, Be, and B to modify fusion reaction networks and enhance charged-particle heating. Doping can also increase bremsstrahlung and introduce additional secondary reactions, including neutron-producing channels. A comprehensive model must therefore evolve the composition and burn fractions while treating radiation and transport feedback self-consistently.

References

A self-consistent treatment of doped plasmas, including full reaction networks, secondary burn fractions, evolving composition, and radiative feedback, remains today an important and yet entirely open nuclear science problem arguably with little if any presence in literature.
