Maximum Orbit Excursion Near Magnetoresonance In A Magnetostatic Wiggler With A Guide Magnetic Field

The complex coefficients of this reduced equation are computed by numerical solution of appropriate eigenvalue problems. In conjunction with these analytical calculations, a highly accurate spectral code has been used to directly simulate the forced, circular shear flows. Both the analytical and the numerical results are in excellent agreement with fluid experiments [3] and show the same qualitative behaviour as the plasma experiments [l, 21, where a detailed quantitative comparison is difficult due to limitations in the experimental information. Our two approaches supplement each other in predicting the trasition to states of ever increasing complexity, even beyond regimes that have so far been experimentally accessible.
