Integral experiments for fast ignition research

Journal article

This paper reviews the important schemes that have been investigated thus far in fast ignition research. Integral experiments for fast ignition research have been conducted utilizing various schemes: (a) double-pulse experiments with two 100-ps pulses injected to a compressed core, (b) gold cone-guided implosion with 100-TW laser pulse heating, and (c) imploded core heated by both a 100-TW and petawatt laser pulses through gold cones. Reviewing these results, several important issues were raised for further development of fast ignition research. The imploded core heated by a petawatt laser through a gold cone showed a 103 D-D neutron increase compared to the one with only the CD shell implosion.
