Structure within the PK-4 Environment
ORAL
Abstract
Complex plasmas have long proven a versatile analog for the study of soft matter systems. On Earth, interparticle interactions can result in particle alignment as well as the formation of various structural states. Unfortunately, the forces behind these interactions are often partially masked by gravity in terrestrial experiments, obscuring the underlying physics. One way of avoiding this issue is through use of the Plasma Kristall-4 (PK-4) device currently in operation on the International Space Station (ISS) [1]. This talk will discuss structural formation observed within the PK-4 on the International Space Station and compare it to that observed using the PK-4 analogue at Baylor University. Results are interpreted using data from numerical simulations of the plasma discharge, dust charging, and plasma-dust interactions. [1] M. Y.
