Fusion neutron and photon neutron producing behavior in the deuterium plasma discharge have been studied on HT-7 superconductive tokamak device by BF3 and 3He proportional ionization chamber implementing the fast time respond neutron flux measurement system. Typical time resolved neutron flux signals have been analyzed in connection with gamma and hard X-ray diagnostic data in the cases of ohmic discharge and lower hybrid wave discharge. Data analysis show that many neutrons are produced by D-D fusion reaction when high-power lower hybrid wave was employed to heat the plasma.
