Abstract :
We have developed PW (0.5 ps/500 J) laser system to demonstrate fast heating of imploded core plasmas using a hollow cone shell target. Significant enhancement of thermal neutron yield has been realized with PW-laser heating, confirming that the high heating efficiency is maintained as the short-pulse laser power is substantially increased to near equivalent power to the ignition condition. According to the results, we are now developing a 10 kJ-PW laser system to demonstrate ignition-equivalent temperature heating.
