Plasma Simulation and Experiment Compared (image) American Physical Society Caption (a) This is a sequence of visible fast camera images of a CHI discharge inside NSTX. The top image shows the expansion of the CHI discharge one thousandth of a second after it is initiated. As shown in the third frame, within three thousandths of a second the plasma has fully filled the vessel; (b) the magnetic structure of a bubble in NSTX as simulated by the NIMROD code.
