Thermal stability of BNCT neutron production target synthesized by ${it in-situ}$ lithium deposition and ion implantation

Ishiyama, Shintaro; Baba, Yuji  ; Fujii, Ryo*; Nakamura, Masaru*; Imahori, Yoshio*

Li$$_{3}$$N synthesis on Li deposition layer was conducted without H$$_{2}$$O and O$$_{2}$$ by ${it in-situ}$ lithium deposition in high vacuum chamber of 10$$^{-6}$$ Pa and ion implantation techniques and the thermo-chemical stability of the Li$$_{3}$$N/Li/Cu tri-layered target under laser heating and air exposure was characterized by X-ray photoelectron spectroscopy. Following conclusions were derived; (1) Li$$_{3}$$N/Li/Cu tri- layered target with very low oxide and carbon contamination was synthesized by ${it in-situ}$ lithium deposition and ion implantation techniques without H$$_{2}$$O and O$$_{2}$$ additions and frequent synthesis of the target is possible. (2) The evaporating temperature of Li deposited layer increased by 120 K after forming the Li$$_{3}$$N layer on the surface of Li. (3) Remarkable oxidation and carbon contamination were observed on the surfaces of Li/Cu and Li$$_{3}$$N/Li/Cu after air exposure and these contaminated compositions formed on the surface of Li$$_{3}$$N/Li/Cu was not removed by Ar heavy sputtering.
