4.2 Fusion Gravimak

The main fusion generator consists of four basic components: reaction chamber, muon generator\injector, accelerator\generator and PTC. The FRC is an armored oblate spheroid six meters in diameter, designed to contain the energy released in the enhanced muon-aided reaction. It is constructed of eight layers of dispersion-strengthened hafnium excelinide with a total wall thickness of 654 cm. A replaceable inner layer of crystalline gallium fluoride 10cm thick protects the structural sphere from heat and radiation effects. Penetrations are made into the sphere for reaction exhaust, pellet injectors, gravitomagnetic fusion initiators, muon particle-beam injectors and normal sensors.

Deuterium(as well as helium-3) from the main cryo tank is heated and fed to interim supply tanks where it is heated further into low-energy plasma. The plasma is confined inside of a high-energy gravity compression field and a magnetic alignment field, with a 20 mega-amp electric charge running perpendicular to the field. Then muons are injected from an adjacent particle accelerator dedicated to the production of these particles. The total instantaneous output of the gravimak is throttleable from 10^3 to 10^5 watts.

High-Energy plasma created during engine operation is exhausted through a central opening in the sphere to the accelerator\generator. This stage is generally cylindrical, 3.5 meters long and 6.3 meters in diameter, constructed of an integral single-crystal duranium frame and pryovunide exhaust accelerator. Plasma created during this stage is then fed a plasma transfer conduit (PTC), where it is sped along and split into an upper and lower stream for optimum annihilation.
