| Computer Modeling The current method being developed at the AARC is a Monte-Carlo particle dynamics simulation. The efficient computer code developed is capable to calculate millions of particle trajectories within hours. It allows investigators to get accurate self-consistent data on plasma density, temperature and velocity.  |
Simulations The use of the particle code together with ion cyclotron radio frequency simulation codes developed in the Oak Ridge National Laboratory demonstrates efficient heating of the plasma by radio frequency waves. The simulations also demonstrate another important requirement for plasma rockets utilizing magnetic nozzles; namely, plasma detachment from the magnetic field lines. The process responsible for plasma detachment is similar to what occurs in solar flares and galactic jets where the expansion of the field occurs faster that that of the plasma. These phenomena are readily observed in nature. |
