Autor: M. Amano, Tetsuaki Moriguchi, Daiki Kamioka, Daisuke Nagae, Yasushi Abe, Yoshihiro Yamato, Shinji Suzuki, Akira Ozawa

Publikováno v: Proceedings of XVII International Workshop on Polarized Sources, Targets & Polarimetry — PoS(PSTP2017).

The Lamb-shift polarized ion source (PIS) was installed as one of the ion sources for the 12UD Pelletron tandem accelerator at the University of Tsukuba Tandem Accelerator Complex (UTTAC) in 1976. The PIS makes it possible to produce highly polarized

Development of a method for the quantitative analysis of hydrogen in minerals with a high-energy proton microbeam

Autor: Kimikazu Sasa, Kohei Furuno, Satoshi Ishii, Yoshihiro Yamato, Masanori Kurosawa, Testuro Komatsubara, H. Ohshima

Publikováno v: Japanese Magazine of Mineralogical and Petrological Sciences. 33:51-61

This report describes our recent development that mainly aims at the quantitative determination of hydrogen concentration in melt inclusions confined in minerals. The method is based on the proton-proton elastic scattering at 20 MeV. Since the stoppi
