Matsuda, Makoto; Osa, Akihiko; Ishizaki, Nobuhiro; Tayama, Hidekazu; Kabumoto, Hiroshi; Nakamura, Masahiko; Kutsukake, Kenichi; Otokawa, Yoshinori; Asozu, Takuhiro; Matsui, Yutaka; et al.

Proceedings of 16th Annual Meeting of Particle Accelerator Society of Japan (Internet), p.1270 - 1273, 2019/07

The JAEA-Tokai tandem accelerator was operated over a total of 138 days, and delivered 16 different ions to the experiments in the research fields of nuclear physics, nuclear chemistry, atomic physics, solid state physics and radiation effects in material in FY2018. Maximum acceleration voltage was 16.6 MV. A new beam attenuator was installed at the entrance beam line of the tandem accelerator to facilitate control of the beam current and minimize stripper foil consumption. The main maintenance items included replacing the pellet chain used for about 68,000 hours and the drive motor for the high voltage terminal generator used for about 9 years. A fault has occurred in the building's oxygen deficiency monitor. This paper describes the operational status of the accelerators and the major technical developments of our facility.

The JAEA-Tokai tandem accelerator complex has been used in various research fields such as nuclear science and material science by researchers not only of JAEA but also from universities, research institutes and industrial companies. This annual report covers developments of accelerators and research activities carried out using the tandem accelerator and superconducting booster from April 1, 2013 to March 31, 2014. Thirty-one summary reports were categorized into seven research/development fields:(1) accelerator operation and development, (2) nuclear structure, (3) nuclear reaction, (4) nuclear chemistry, (5) nuclear theory, (6) atomic physics and solid state physics (7) radiation effects in materials. This report also lists publications, meetings, personnel, committee members, cooperative researches and common use programs.

Issues associated with radiation protection after Fukushima Daiichi Nuclear Power Plant disaster

Yamasoto, Kotaro

Gijutsushi, 27(11), p.8 - 11, 2015/11

Various analysis reports focused on Fukushima Daiichi Nuclear Power Plant disaster have been published from government, national diet, private group and Tokyo electric power company. Japan Health Physics Society (JHPS) analyzed these reports on perspective of radiation protection, and has reported towards the national and international society as "second-order recommendation report". What are radiation protection issues that have been found from these analysis reports? What is the direction of the goal of radiation protection system at the time of nuclear accident? From the results of these analyzes, many challenges have been found in current nuclear disaster prevention system.

Acquisition and provision of conference proceedings in the science and technology field; Case of Japan Atomic Energy Research Institute Library

Ikeda, Kiyoshi

Joho No Kagaku to Gijutsu, 55(5), p.219 - 223, 2005/05

Conference proceedings are information resources used for researchers to access latest research trends. Although they are important materials that should be collected by the library, it is generally very difficult to acquire them because they are not commercially available. JAERI (Japan Atomic Energy Research Institute) Library collects about 19,000 proceedings and makes them available for the researchers. This paper introduces JAERI Library's experience in acquiring conference proceedings in a variety of ways including collecting conference information from academic societies or researchers, utilizing INIS (International Nuclear Information System) database as well as provision of conference proceedings. JAERI-Conf series, which are the proceedings of conferences hosted by JAERI and published as JAERI's research reports, are also introduced.
