Abstract :
Rotating plasma spheroids are observed in a capacitively coupled radio-frequency discharge containing grown dust particles. These plasma spheroids are regions of slightly enhanced emission that rotate along the circumference of electrodes. This effect is not observed systematically, and when it occurs, the number and the speed of the spheroids can vary with the discharge parameters. These spheroids have been evidenced by using high-speed imaging.
