Imploded Plasma Heating by Irradiation of Heating Laser through a Cone with a Hole for Fast Ignition

It is of great importance for the fast ignition research to investigate the heating properties of the imploded core plasma by injection of the heating laser. The open-end cone was introduced recently. An expanding self-emission of x-ray from the core plasma near the cone tip was observed after the heating laser irradiation through the cone. It indicates that the core plasma was heated by the heating laser. (paper)
