Double-shell targets at low electron-beam power
Conference

OSTI ID:7333554
Electron beam requirements for obtaining measurable compressional neutrons on present-day accelerators with double-shell targets are discussed. In such a target, the inner pusher is separated from the outer ablator-pusher region by a low-density buffer gas. Because of velocity multiplication and spherical convergence, the inner pusher moves at a higher implosion velocity. The buffer gas serves to enhance the elasticity of the collision of the outer and inner pushers. The target has the advantage of small fuel mass--as for a small, thick-shell target--but without the requirement of a tighter beam pinch. Unlike the other two targets shown, a double-shell target scales to breakeven.
