Fast ignitor target studies for HiPER

Abstract

The HiPER facility has been proposed recently to demonstrate fast ignition of laser driven inertial fusion targets. According to the present design, HiPER will have a 3ω, multi-beam, multi-ns-pulse of about 250 kJ and a 2ω or 3ω ignition beam delivering 70 kJ in about 15 ps. We present here studies on laser-driven fast-ignitor targets driven by 100-300 kJ compression pulses, followed by 70-100 kJ ignition pulses.
