TL;DR: In this paper, the behavior of hydrogen and deuterium retained in the graphite tiles placed in the dome top unit, the outer divertor unit and the outer baffle plate of JT-60U with W-shaped divertor were investigated by secondary ion mass spectroscopy and X-ray photoelectron Spectroscopy (XPS).

TL;DR: The behavior of hydrogen isotopes in boron was studied by XPS and TDS as discussed by the authors, who found that deuterium retention at 573 K was decreased less than 35% compared to that at room temperature.

TL;DR: In this paper, the growth rate of the boron coating film and the hydrogen retention were evaluated by changing the total pressure, the discharge power, and the substrate temperature, and it was shown that the growth rates are not controlled by the chemical form of B-H bond, but by that of b-B bond.

TL;DR: In this article, a PACVD apparatus was designed and fabricated at Shizuoka University in order to prepare high-pure boron coating films, and some parameters, such as feeding gas concentration, substrate temperature and CVD input power, have been optimized to prepare pure BORON coating films.

TL;DR: In this paper, deuterium ions were implanted into SiC to elucidate the interaction mechanism between Deuterium and SiC, and the chemical states of Si and C were studied by X-ray photoelectron spectroscopy (XPS) and thermal desorption behavior of deutereium was analyzed by thermal Desorption Spectroscopy(TDS).
