概要	Effects of radiation damage on deuterium trapping in tungsten were investigated using SiMS/NRA and TDS techniques. Radiation damage of similar to 4.8 dpa was produced by 300 and 700 keV hydrogen ions, then deuterium ions were implanted at 473 K to fluences of 0.5-8.0 x 10(24) D(+)/m(2). Deuterium concentration at -0.1 mu m in depth was saturated at the lowest fluence (-5.0 x 10(23) D(+)/m(2)), while the D retention at -1.0 mu m deep was not saturated at the highest fluence of -8.0 x 10(24) D(+)/m(2). On the other hand, deuterium behavior Simulated by the TMAP7 code showed that the defects were filled with the implanted D from the top surface and all of the traps were filled at the fluence of similar to 7.5 x 10(22) D(+)/m(2), which was much lower than the fluences in this experiment. TDS spectra suggested that the implanted D was trapped at the radiation-induced defects which had desorption peaks at similar to 770 and similar to 920 K. (C) 2009 Elsevier B.V. All rights reserved.
