Abstract Text:
An array of floating electrostatic probes have been deployed on the Maryland Centrifugal Experiment (MCX). These probes provide a means for for better understanding the behavior of the plasma waves and instabilities, in particular interchange and drift modes, in a supersonic rotating plasma. Of particular interest are the growth and evolution of low mode number instabilities which are less velocity-shear suppressed at low mach numbers and lead to sudden drop in plasma voltage and rotation. In addition the probes provide an additional means of examining the rotation profile in the outer regions of the plasma. The 2D array of probes will allow determination of azimuthal and axial wavenumbers. This could allow a differentiation between finite k.B drift-type modes and flute-type interchange modes.

If possible I would like to be placed near the other Maryland authors, W.C. Young and C. A. Romero-Talamás. I may have accidentally submitted twice. Please disregard any others.
