Fusion target and fusion ignition method

摘要

PPROBLEM TO BE SOLVED: To provide a target and an ignition method for nuclear fusion which enable the efficient ignition for the nuclear fusion reaction of fuel. PSOLUTION: The target 1 for nuclear fusion comprises a main fuel layer 11 placed so as to surround the first domain when viewed from the central part C; a main fuel section 10 which has an ablator layer 12 placed on the outer periphery of the layer 1; and a section 20 for the fuel to be ignited which has a layer 21 of a fuel to be ignited placed for the second domain other than the first domain when viewed from the central part C and an ablator layer 22 placed on the outer periphery of the layer 21. The target has an opening 31, a corn member 30 which separates the fuel sections 10 and 20 is formed and the layer 21 of the fuel to be ignited is so constituted that it can be guided to the central part C through the opening 31 when it is irradiated with laser light.
