GROWTH OF SURFACE INSTABILITIES IN A LINEAR PINCHED DISCHARGE
Results are reported from experiments on the growth of instabilities in a linear pinched discharge in argon. These discharges were produced in a tube 15 cm in diameter and 50 cm long at pressures of 0.1 to 1.0 mm mercury and with currents of 40 to 150 kamp. Results revealed the presence of surface instabilities typical of many single-shot photographs of the discharge taken through the side of the tube with a Kerr cell camera. The irregularities on the plasma surface first appear when the column is expanding from the first axial bounce and grow while the plasma is being accelerated toward the axis of the discharge tube between the first and second bounces.
