TL;DR: Ce2%:6LiCaAlF6 (6LiCAF) single crystal (nominal composition) with 2 mm in diameter and 50 mm in length was grown by the micro-pullingdown method as mentioned in this paper.
Journal ArticleDOI
Crystal growth, optical properties, and α-ray responses of Ce-doped LiCaAlF6 for different Ce concentration
Takayuki Yanagida,Akira Yoshikawa,Yuui Yokota,Shuji Maeo,Noriaki Kawaguchi,Sumito Ishizu,Kentaro Fukuda,Toshihisa Suyama +7 more
TL;DR: In this article, LiCAF single crystals were grown by the micro-pulling-down method and optical properties, including absorption coefficient, and photoluminescence emission spectra were measured.
Journal ArticleDOI
Neutron–gamma discrimination based on pulse shape discrimination in a Ce:LiCaAlF6 scintillator
Atsushi Yamazaki,Kenichi Watanabe,Akira Uritani,Tetsuo Iguchi,Noriaki Kawaguchi,Takayuki Yanagida,Yutaka Fujimoto,Yuui Yokota,Kei Kamada,Kentaro Fukuda,Toshihisa Suyama,Akira Yoshikawa +11 more
TL;DR: In this article, the decay time of the scintillation light pulse is converted into the rise time through an integrating circuit, which is used to discriminate between gamma-ray and neutrons.
Journal ArticleDOI
Pr3+-doped fluoro-oxide lithium glass as scintillator for nuclear fusion diagnostics.
Yasunobu Arikawa,Kohei Yamanoi,Tomoharu Nakazato,Elmer Estacio,Toshihiko Shimizu,Nobuhiko Sarukura,Mitsuo Nakai,Takayoshi Norimatsu,Hiroshi Azechi,Takahiro Murata,Shigeru Fujino,Hideki Yoshida,Kei Kamada,Yoshiyuki Usuki,Toshihisa Suyama,Akira Yoshikawa,Nakahiro Sato,Hirofumi Kan +17 more
TL;DR: Time-resolved measurements of neutron scintillating properties of a custom-designed Pr3+ (praseodymium)-doped lithium (Li) glass reveal that it can clearly discriminate fusion neutrons from the much stronger x-rays signals.
Journal ArticleDOI
Fabrication and characterization of large size 6LiF/CaF2:Eu eutectic composites with the ordered lamellar structure
Noriaki Kawaguchi,Kentaro Fukuda,Takayuki Yanagida,Yutaka Fujimoto,Yuui Yokota,Toshihisa Suyama,Kenichi Watanabe,Atsushi Yamazaki,Akira Yoshikawa +8 more
TL;DR: In this article, a large size LiF/CaF2:Eu eutectic composites of 58mm diameter and 50mm thickness were produced by the Bridgman method.
