Abstract
To demonstrate the feasibility of the fast ignitor scheme,1,2 a 100 TW Petawatt Module laser (PWM) was illuminated onto an uniformly imploded spherical shell target. The neutron yield is enhanced from below 105 up to 106 for the first time and agree with those estimated from the simultaneously detected high energy deuteron yield and spectrum. A few hundred keV deuterons collide with the cold deuterons in core. Without PWM, no neutrons are observed above the detection threshold of 105.
