Preparations for pB11 tests in the FF-2B dense plasma focus

Frontiers in Physics
The dense plasma focus (DPF) device has great potential as a fusion energy generator using hydrogen-boron (pB11) fuel1. Experiments using deuterium have already demonstrated mean ion energies >200 keV, in the range needed for burning pB112.
