An Experimental Investigation of Dense Ion Flow in the Presence of a Transverse Magnetic Field.
Abstract
The interaction of dense (10 to the 8th power-10 to the 10th power ions/cc) single and counterstreaming Cs(+) ion beams with a transverse magnetic field has been examined. Magnetic field strengths are in the range of 0-10 gauss, yielding electron radii of curvature small compared to beam diameter. Ion radii of curvature, from large ion mass and velocity is much greater than beam and testing chamber dimensions. Application of transverse fields above critical levels of about 3 gauss causes rapid increases in plasma potential turbulence for both single and counterstreaming beams. Heating of electrons is observed, and growth in ion density fluctuation is rapid for field levels > than about 3 gauss. Ion transverse velocity build up in counterstreaming beam configurations appears in excess of single beam flow across the field, while ion density fluctuation build up in the single beams exceeds that of the counterstreaming flow. Wave growth for injected ion density waves has been examined as functions of injected wavelength, magnetic field strength, and wave traversal distance across the field.
