The exact thrust and velocity of the plasma jet as well as power losses due to ionization,
thermal radiation, Bremsstrahlung radiation, and grid dissipation need to be measured
in the experimental device.

• Charged particles are tied to fieldlines (electrons
and protons gyrate in opposite directions).
• Even when the plasma is effectively collisionless
( mean free path >> typical lengthscales ) the
magnetic field causes the plasma to behave
• The gyroradius defines the len ...

Variable Specific Impulse Magnetoplasma Rocket
The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is an electromagnetic thruster for spacecraft propulsion. It uses radio waves to ionize and heat a propellant, and magnetic fields to accelerate the resulting plasma to generate thrust. It is one of several types of spacecraft electric propulsion systems.The method of heating plasma used in VASIMR was originally developed as a result of research into nuclear fusion. VASIMR is intended to bridge the gap between high-thrust, low-specific impulse propulsion systems and low-thrust, high-specific impulse systems. VASIMR is capable of functioning in either mode. Costa Rican–born American scientist and former NASA astronaut Franklin Chang Díaz created the VASIMR concept and has been working on its development since 1977.VASIMRs units for development and test have been assembled by the Ad Astra Rocket Company, headquartered in the city of Houston, Texas, United States.
