Comments on “A simple model of ion beam heated ICF targets” by R. G. Evans

Abstract

In a recent study R. G. Evans developed an analytic model for ICF targets heated by heavy ion beams in order to show the differences to laser beam heating. However, these differences are really not very pronounced. In fact, Evans' model should be directly applicable to describe exploding pusher foil targets. In addition, Evans' scaling law for the ablation pressure PA with target density ρ0 and particle beam intensity Ib,is identical to the scaling found for laser targets with tamped flow (Ahlborn, 1981).
