Abstract
The transport of low-energy charged particles moving along magnetic field lines is considered. We point out that particles accelerated at CIRs at larger heliocentric distances and moving inward along the spiral field lose energy and decelerate even in a purely scatter free case. This results in a sizeable reduction in intensity. Scattering increases the transit time, and in general increase the amount of cooling and modulation by a considerable factor. Numerical results obtained from a model including convection, adiabatic focusing, cooling, and optional pitch angle scattering are presented.
