IFMIF(International Fusion Materials Irradiation Facility)の加速器構成材料であるAl, Cu, Wの重陽子入射による放射化断面積の測定をTIARA施設のAVFサイクロトロンを用いて行った。測定対象とした反応は$$^{27}$$Al(d,x)$$^{27}$$Mg, $$^{24}$$Na, $$^{nat}$$Cu(d,x)$$^{62,63}$$Zn, $$^{61,64}$$Cu, $$^{nat}$$W(d,x)$$^{187}$$W, $$^{181-184,186}$$Reで、エネルギー領域は22$$sim$$40MeVである。得られた値を他の実験値及びACSELAMの計算値と比較した。

Measurements of deuteron-induced activation cross sections for IFMIF(International Fusion Materials Irradiation Facility) accelerator structural materials(aluminum,copper,tungsten) were performed by using the AVF cyclotron in TIARA. We obtained the activation cross sections for the reactions $$^{27}$$Al(d,x)$$^{27}$$Mg, $$^{24}$$Na, $$^{nat}$$Cu(d,x)$$^{62,63}$$Zn, $$^{61,64}$$Cu, and $$^{nat}$$W(d,x)$$^{187}$$W, $$^{181-184,186}$$Re in 22-40 MeV rigion. The present results were compared with other experimental ones and the data in the ACSELAM library.
