Measurement of ion acceleration in the magnetic nozzle of an ecr plasma thruster

Study of the plasma near the plasma electrode by probes and photodetachment in ECR-driven negative ion sourceM. Svarnas, Stéphane Bechu,

Different ion species (rare gases, alkali, metallic) have been injected on the axis of the MINIMAFIOS - 10 GHz - Electron Cyclotron Resonance Ion Source which is the basics of the 1+

In order to know the contribution of the plasma chamber walls in the recycling process, we stopped the source to replace the coaxial tube by a new one.. No deposits could be

We show that resonant acceleration of heavy ions by nonlinear magnetic waves in the reconnection outflow region is more e ffective for heavy ions and/or for ions with a larger

ionized ions in an ECRIS. The special difficulties arise from its physical and chemical properties. Lithium is a metal, which tends t o condense at any cool place in

White beam X-ray imaging and focused beam radiography were used to assess the effect of nozzle electrification on the near-field spray characteristics from an airblast atomizer.

general form of the potential relief (or in the presence of a magnetic field) the particle overcoming the saddle point with small kinetic energy will not come back. So,

At a higher gas pressure and microwave power, at about 10-5 Torr and 1 kW, respectively, a total beam current up to 10 mA was extract- ed from the chamber. This amount of ions
