Abstract
An analytic model for the dynamics of fast ignition is studied for the case in which the proton beam heats the fuel by generating a subsonic heat wave. It shows that the temperature, the confinement parameter, and density of the hot spot required for ignition decrease with the proton range R. Our calculations together with the results of supersonic model, allow for the determination of the optimum time available for ignition as ti,opt ≈ 1.47×10-6ρ-10 s
