Computer simulation studies of strong proton rings

Abstract
Results are reported from a numerical simulation study on the propagation of a rotating proton pulse and the formation and trapping of the resulting strong proton ring. It is observed that the self‐magnetic field has a very pronounced effect on the dynamics of such systems. In addition, it is observed that rings trapped in a magnetic mirror field are r, z stable for the entire confinement time tested of 550 nsec and suffer neither axial nor radial particle losses.
