Recent Progress of Fast Ignition Research at Institute of Laser Engineering, Osaka University

The concept of “Fast ignitor” has been proposed several years ago in inertial confinement fusion¹. This new approach may require compressed core structure and density already demonstrated and may lead to a very high gain of the thermonuclear fusion. After brief introduction of the fast ignition, we report the current status of the fast ignitor research at the Institute of Laser Engineering, Osaka University, Japan.
