Phase Space Coordinates of Long Lifetime Trapped Radiation from Stoermer Mapping.
Abstract
The concept of an 'essentially closed' manifold and several theorems on a plane mapping are introduced and applied to a 'Stoermer mapping' for a particle trapped in a dipole magnetic field. The trapped region is found to be divisible into many subregions in any one of which a particle forever remains confined. Alternatives are given to Dragt and Finn's interpretation that homoclinic points exist. A method is given of determining if they do exist. Numerical examples are given of regions of phase space where protons should have a long lifetime. (Author)
