Spectral Asymmetry Due to Magnetic Coordinates
Authors: Jong-kyu Park,, Allen H. Boozer, and Jonathan E. Menard
Abstract:
The use of magnetic coordinates is ubiquitous in toroidal plasma physics, but the distortion in Fourier spectra produced by these coordinates is not well known. A spatial symmetry of the field is not always represented by a symmetry in the Fourier spectrum when magnetic coordinates are used because of the distortion of the toroidal angle. The practical importance of spectral distortion is illustrated with a tokamak example.
