Abstract
Experimental observations of plasma self-oscillations are presented. In the current regime limited by the cathode temperature of a continuous multipolar discharge, they appear for low gas pressure (collisionless plasma), low cathode heating current and above a discharge voltage threshold. Their frequency and amplitude are strongly dependent on the discharge parameters. The scaling laws of their variation and an example of a period-doubling route to chaos are reported.
