Analytical Eigenvalue Solution for ηi Modes of General Modewidth
Artikel i vetenskaplig tidskrift, 2004

The eignevalue problem of ion temperature gradient (ITG) modes in a reactive fluid model for general mode width was solved. This solution was iterative and suitable for use in transport codes. The correlation length tends to be close to that of the linearly fastest growing mode, in nonlinear simulations with absorbing boundaries for both long and short wavelengths. Additional effects of magnetic shear, magnetic q and elongation on the transport through their effects on the correlation length can be obtained by using a single mode at the correlation length for the transport.
