Abstract
We compared the experimentally measured neutron emission rate with the emission rate calculated by using the simple Fokker-Planck equation with the experimental temperature and density profiles, and the deuteron density evaluated by a spectroscopy in peripheral region in LHD. The neutron emission rates evaluated by the FIT3D-DD code are approximately two times higher than experimental results in the typical magnetic configuration of LHD. In the case of low fast-ion confinement, the calculations are approximately four times higher than experimental measurements.
