Abstract

Abstract

The gas fill near the Au wall along the inner laser cone is the main region which stimulates SRS instabilities. At this region, pressure balance and energy balance between the inside and the outside of inner laser cone path are obtained. A plasma scaling model in ignition hohlraum of ICF has been developed. Capsule performance, laser facility parameters, and laser-plasma interaction (LPI) physics are related by this scaling model. A 350 eV ignition hohlraum design is proposed according to the model. Compared with the designs published before, this design could reduce LPI development of inner laser cones better, but put forward more pressure on laser facility design.
