Samenvatting

A potential buildup in front of a magnetized cascaded arc hydrogen plasma source is explored via .vector.E * .vector.B rotation and plate potential measurements. Plasma rotation approaches thermal speeds with max. velocities of 10 km/s. The diagnostic for plasma rotation is optical emission spectroscopy on the Balmer-beta line. Asym. spectra are obsd. A detailed consideration is given on the interpretation of such spectra with a two distribution model. This consideration includes radial dependence of emission detd. by Abel inversion of the lateral intensity profile. Spectrum anal. is performed considering Doppler shift, Doppler broadening, Stark broadening, and Stark splitting. [on SciFinder (R)]
