  1. 15. A first review of facility effects on electric thruster testing
    Mr Florian Marmuse (LPP - UPMC)
    02/03/2017, 16:00
    Poster
    Evaluating a thruster performances in a representative operational environment is a key milestone towards its use in space. However, the limited size and pumping speed of currently available test facilities limit the validity of most performance measurements, from the plume divergence to the thruster lifetime expectancy. Based on a literature review, this poster features a panel of the...

  2. 21. Carbon-based materials for cathode neutralizers in electric propulsion
    Dr Grazia Cicala (CNR-NANOTEC)
    02/03/2017, 16:00
    Poster
    Neutralizer cathodes used as electron sources represent a key component of electric propulsion (EP) systems for spacecrafts. In EP systems such as electric propulsion thrusters, ion engines and hall thrusters, a positive ion beam is ejected at high speed to produce thrust. Over time, the ion beam expands and becomes fuzzy for the space charge formation that reduces the thrust and causes arcing...

  5. 0. Small rf plasma generator for air
    Marco Cavenago (LNL)
    02/03/2017, 16:00
    Poster
    Complex plasma devices as thrusters or ion sources for fusion and their physical models at reduced size, as the negative ion source NIO1 developed by Consorzio RFX and INFN-LNL, rely on several accessories, like coil shielding, cesium vaporizers, probes and bias electrodes, which needs to be separately tested , both to avoid delays in the major source schedule and to better understand...

  6. 13. Wall interactions in Hall Effect Thruster, investigation with bidimensional Particle-in-cell model and simulation
    Mr Antoine Tavant (LPP)
    02/03/2017, 16:00
    Poster
    Hall effect thrusters (HET) are one of the main technology used and studies for spacecraft propulsion. Grid-less, they present net advantages, resulting of an increasing need for predictive and accurate models, and a better understanding of the complex behavior of the plasma. HETs consist of three main components : a magnetic circuit used to produce a mostly radial magnetic field; an...
