SizeDHe3FusionEngine:
% Design a driven D-He3 fusion engine.
This treats the plasma as a volume. It does a mixing analysis of the
various side reactions to produce a power flow. It can also take
your power numbers and use them to compute the engine mass. The fields
of d are pFusion, pSynch, pBremss and pNeutron.
pGasBox is the power needed to ionize the mass flow in the engine.
This function allows for continuous heating through the input pRMF
The amount of external power to maintain fusion varies with the design.
The output is in the form of a data structure. If you don't specify
an output it will print the results in the command window.
For the filename you can type in xxx.tex or just xxx.
Type DesignDHe3FusionEngine to see a 10 MW engine. It uses the
numbers in the default datastructure.
