Borane (BmHn), Hydrogen rich, Proton Boron fusion fuel materials for high yield laser-driven Alpha sources

Popis výsledku v původním jazyce

We propose for the first time, a new fuel -material for laser -driven Proton Boron (P -B) fusion nuclear reactions. We propose, Hydrogen rich, Borane (BmHn) materials as fusion fuel as compared to Boron Nitride (BN) presently used. We estimate more than 10 -fold increase in the yield of nuclear fusion reactions, and Alpha -pr ticle flux, when, for example Ammonia Borane (BNH6) laser -target material will be used compared to the state of the art normalized flux similar to 108 Alphas/sr/J from BN targets. BNH6 contains similar to 1000x higher concentration of Hydrogen compared to BN. We report the manufacture of the first solid-pellets Ammonia Borane laser-targets. To obtain high Flux Alpha sources from repetitive lasers we propose new BNH6 target geometries: liquid (molten) droplets/jets; or translated tape- or disc-targets coated with BNH6 powder. Targets would be irradiated in low pressure, ambient buffer gas. To enhance the fusion/Alpha yield of ultra-high intensity PetaWatt laser-target interaction we propose nano- and micro-structured Borane targets. As applications, we propose to use the Alpha-driven nuclear reactions inside the laser-driven Borane targets for new schemes to produce short-lived medical radioisotopes. Such laser-driven radioisotope beamlines would be installed directly in hospitals. Borane materials, like Diborane (6), B2H6, are also proposed as nuclear-fuels for laser-driven Proton-Boron fusion energy generation. The high dilution of Boron in Hydrgen B/H = 33% would need to be further enahnced to B/H < 15% to cut radiation losses from the hot and dense fusion pellet.
