Investigating The Angular Momentum Of Dusty Plasma Multi-Rings, Isaac M. Long, Kiser Z. Colley

ONU Student Research Colloquium

Multi-ring dusty plasma systems were created using a grooved rf electrode. These complex plasma systems had distinct sections consisting of a certain number of rings (1 ring section, 2 ring section, 3 ring section, 4 ring section). These rings had the tendency to rotate azimuthally about the center of the electrode, which allowed for a sectional angular velocity (ω) to be calculated. It was determined that as the number of dust rings (therefore the mass) increased, ω decreased which agrees with conservation of angular momentum. The pressure was also varied and it was found that as pressure increased, the width …
