Abstract

The tomography measurement, with a help of a newly developed analysis called Fourier-rectangular function (FRF) transform, reveals the properties of the bursting phenomenon occurring at the lower operational boundary of the filling pressure in a cylindrical plasma produced with a helicon source. The analysis provided a clear difference in the spatiotemporal structure between the bursting and quiescent states in the phenomenon.
