Analysis of multifrequency interferometry in a cylindrical plasma
… taken in a cylindrical plasma on the Variable Specific Impulse Magnetoplasma Rocket (VASIMR) project. Standard data analysis based on a thin beam model neglecting refraction yields inconsistent electron densities and density profiles for different frequencies. This work focuses on the …

Ion flux maps and helicon source efficiency in the VASIMR VX-100 experiment using a moving Langmuir probe array
… T) external magnetic fields in the VASIMR (Variable Specific Impulse Magnetoplasma Rocket) VX-100 experiment. The probe array was swung through an argon plasma revealing a detailed 2-dimensional cross section. Neutral input flow and probe collector bias voltage were scanned from pulse to …

Theoretical studies of the VASIMR plasma propulsion concept
This dissertation was motivated by the Variable Specific Impulse Magnetoplasma Rocket (VASIMR) project. The VASIMR device has a magnetic mirror configuration and consists of three main components: a low energy helicon plasma source, which creates cold plasma via rf-discharge; an ion …
