Keywords:Tungsten, plasma implantation, heavy ion implantation, Deuterium retention behavior, neutron implantation

To evaluate the deuterium (D) retention behaviors in tungsten with various damage distributions, Fe ions were implanted into tungsten with various damage concentrations. Thereafter, 1.0 keV D2+ implantation and thermal desorption spectroscopy were performed to evaluate the D retention behaviors. The same experiments will be performed on neutron irradiated tungsten and compared with Fe irradiation.
