Estimates of maximum trappable ion beam power in plasma channels

Conservation laws and solutions to the equations of motion for single particles have been used to obtain greatest lower bounds on the ion beam power that can be injected into and confined within plasma channels. These bounds are of use in the evaluation of proposed light-ion-driven inertial confinement fusion (ICF) experiments and reactor concepts. Simple estimates of trappable power based on conservation laws will be compared with estimates based on solutions to the equations of motion. Consequences of the results of these calculations to current design studies will be discussed
