EXPERIMENTAL MAGNETOHYDRODYNAMIC TURBULENCE INVESTIGATIONS

Abstract

An experimental program on magnetohydrodynamic turbulence is presented. the experimental apparatus, which is essentially a linear pinch evice, is described. Experimental results which are discussed include electrical current waveforms, Kerr cell camera photographs, and magnetic field probe measurements. Kerr cell photographs clearl show the breakup of the plasma column due to instabilities; and a statistical study was begun of the sizes of the instabilities. A technique is described using an x-y oscilloscope to obtain an estimate of the correlation between two magnetic probe signals for various distances between the probes. From these data, we hope to obtain the energy spectrum and an estimate of isotropy of the turbulence. (Author)
