Matrix Methods of Cosmic Ray Propagation
- 81 Downloads
Matrix methods of cosmic ray propagation involve reduction of the propagation equations to a set of coupled linear differential equations. This reduction results in an elegant separation of local propagation effects, such as nuclear fragmentation, from global effects such as pathlength distribution. The matrix equations are solved by simple methods. We show how the reduction to linear form is made for ionization loss and solar modulation. In addition, we show how to calculate propagation errors.
