High thermonuclear neutron yield by shock multiplexing implosion with GEKKO XII green laser

Abstract
High aspect ratio pellet targets are ablatively imploded with twelve green beams of GEKKO XII. Multiplexing of shock waves with a quasi-tailored pulse is performed successfully in DT fuel compression. The highest neutron yield achieved is 1.25 × 1012 per shot. The development of new diagnostics such as neutron activation and secondary fusion reaction diagnostics is also presented.
