Studies were made of the quasi-stable pinch produced by a relatively long duration low voltage capacitor discharge (5ms, 3kv) in a 600 cm long, 15 cm diameter metal tube. Current-voltage characteristics, spectra and magnnetic probe measurements were the most productive instrumental techniques for the study of gas temperature, stability, and wall material contamination. The magnetic field distributions obtained with the magnetic probes showed an interesting regularity in time and space for certain values of gas density, gas current, and applied axiai magnetic field. It was possible to obtain complete current distributions for this case from the measurements of the three components of magnetic field. The current distribution was found to have a helical notch of reduced current density and the distribution rotated with an angular velocity of 20,000 revolutions per second. The helical regularity may be a hydromagnetic wave of the Alfvien type. (auth)
