Effect of recombination and ionization on the analysis of Mach and single probes in weakly and strongly magnetized plasma of DiPS and MAP-II devices

초록

For the analysis of atomic processes such as recombination and ionization in the divertor plasma, we have developed a rotatable fast-scanning multiple probe system, which is composed of single, Mach, negative ion, and/or emissive probes along with Thomson scattering and optical emission spectroscopic systems at the MAP-II(Material and Plasma) divertor simulator with low magnetic field(about 200 G). This probe system can measure the spatial variations of electron density, electron temperature, negative ion density, flow velocity and/or plsama potential with probe theories including the atomic processes such as ionization and recombination.
