Deuterium-Helium 3 Engine Design

Aneutronic fusion engines have the potential to revolutionize in-space transportation. A single function, DesignDHe3FusionEngine, generates a point design for a fusion engine for the Deuterium-Helium 3 reaction. It assumes a cylindrical geometry. It allows you to set separate temperatures for each reactant and the electrons to model non-equilibrium plasmas. It automatically computes neutron shielding, heating power, radiator mass and refigerator mass and specific power. This function allows you to do rapid trade studies of different temperatures, reactant number densities and other properties. The function will automatically generate a latex table with the inputs and all results for inclusion in latex files. This table was generated using the toolbox CreateHTMLTable function.
