  1. Theoretical studies of the VASIMR plasma propulsion concept

    Arefiev, Alexey VladimirovichThe University of Texas at Austin2002

    … 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 cyclotron-resonance heating (ICRH) section, which is …

  2. Ion flux maps and helicon source efficiency in the VASIMR VX-100 experiment using a moving Langmuir probe array

    Olsen, Christopher ScottRice University2009

    … (∼1.5 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 …

  3. Analysis of multifrequency interferometry in a cylindrical plasma

    Kraft, Daniela JuttaThe University of Texas at Austin2006

    … 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 development of a model for the wave propagation …

  4. Preliminary Design of an Asteroid Hopping Mission

    Scheppa, Michael D.

    … Variable Specific Impulse Magnetoplasma Rocket (VASIMR) was and instrumental piece in maximizing the number of NEAs visited. Once the spacecraft was designed, acceptable power supply options were investigated. The VASIMR VX-200 requires 200 kilowatts of power to maintain thrust. This creates the …

  5. Virtual metrology for plasma etch processes.

    Lynn, ShaneNational University of Ireland Maynooth2011

    … variable specic impulse magnetoplasma rocket (VASIMR) engine, a plasma-based space propulsion system. The temperature monitoring system uses optical emission spectroscopy (OES) measurements from the VASIMR engine plasma to correct temperature estimates in the presence of modelling error and …
