Abstract
Turbulence generated by a rapidly imploding current sheath in a high-voltage pinch has been investigated by C laser scattering and by emission spectroscopy of forbiddenline satellites in helium. Waves indicative of a saturated ion-sound instability are seen in the current sheath. In a region well behind the sheath, waves are seen with wave numbers near . These waves may be the result of mode coupling from short-wave-number turbulence generated earlier by the passage of the current sheath.
