Abstract :
In this paper we discuss a concept of a large-size-pellet ion-beam inertial confinement fusion(ICF) in which a DT fuel pellet is more than several tens mg. In the large-size-pellet ICF the fuel is compressed to less than 1000 times the solid density, for example about 100 times the solid density in order to realize ρR > 1 ∼ 3g/cm2. Because of the low compression ratio, constraints required for the uniform fuel implosion are relaxed compared with those for a high-compression implosion of a small pellet. This concept of the large-size-pellet implosion may present another approach to ICF. In this paper we present a simple estimation for the concept and one-dimensional numerical analyses for the large-size-pellet implosion. A simple linear estimation for the Rayleigh-Taylor instability presents that the fuel pellet may not be destroyed by the instability.
