Abstract
The non-Maxwellian effect of D-T ions in an inertially confined plasma was studied, and it was found that the reduction of the fusion reaction rate due to such a non-Maxwellian effect in the recent high-neutron-yield implosion experiments is not so drastic. Although the nonuniformity effect actually seems to be the main reason for explaining the difference of the neutron yield between the experiment and the 1-D simulation, the difference of a factor of 0.6∼0.7 in neutron yield can be explained by taking account of such a non-Maxwellian effect.
