Physics Colloquium - Imaging studies of self-organization in plasmas

Presented By:

Akio Sanpei from Kyoto Institute of Technology

Self-organizations are interesting and universal phenomena in various plasmas. For example, spontaneous three-dimensional deformation due to MHD phenomena in axisymmetric fusion plasma is an interesting topic. In low- temperature plasma, it is well known that negatively charged dusts interact with each others and make an ordered state. Imaging diagnostics are useful and intuitive approach to study such various scale self-organization phenomena. In order to study about self-organization in plasmas, we are developing imaging systems about visible light, SXR, electron and ion fluxes.

In this talk, we introduce our imaging studies of self-organizations in reversed field pinch, non-neutral plasma, and dusty plasma.
