In the large tandem mirror device GAMMA 10/PDX, a divertor simulation experimental module (D-module) with a V-shaped divertor target have been installed in the end-mirror. A massive gas injection of hydrogen and noble gases (argon and xenon) into the D-module during hydrogen plasma irradiation onto the target was performed, and plasma detachment from the target was investigated. Electron temperature measured by Langmuir probe array on the target was significantly reduced from a few tens of eV to 
3 eV, and particle flux was also reduced. A bright H
emission in the upstream region of the D-module and strong reduction near the target were observed by a two-dimensional image of H emission in the target observed with a high-speed camera. Molecular activated recombination (MAR) process is expected to contribute to the reduction of the electron temperature and the particle flux.

一般産業界の金型クリーニングや塗装剥離等に広く用いられるようになってきているレーザ技術の除染への適用可能性を検討するため、放射能で汚染した材料を用いて除染試験を行った。試験結果から、汚染形態や対象物の形状等を考慮することで、適用可能な見通しを得た。
