Abstract :
Images of visible light emission from flux ropes during plasma relaxation are presented. Multiple images are used to gain insight into the dynamics of driven/dissipative plasma relaxation processes in finite-β plasmas. A fast-gated (40-200 ns) intensified charge coupled device (ICCD) camera generates time-resolved images of 1-3 flux ropes in the reconnection scaling experiment (RSX) device. During relaxation, flux ropes are observed to evolve toward states characterized by the presence of single and multiple helical mode structures.
