Radio Astronomy Frequency Committee in Japan Yoshihiro NAOJ

Radio Astronomy Frequency Committee in Japan ＣＨＩＫＡＤＡ, Yoshihiro (NAOJ) The 3 rd IUCAF Summer School, 3 June 2010 1

Role of the Committee • Speak up for radio astronomers as the unified public opinions of Japanese astronomy community Japanese radio astronomers’ community Radio Astronomy Frequency Committee in Japan Regulatory bodies demand for unified opinion International regulatory bodies (ITU) National regulatory bodies (Ministry of Internal Affairs and Communications) The 3 rd IUCAF Summer School, 3 June 2010 Industries Industries 2

How can we get unified public opinions? • Varieties of interest situations – Observing bands • HF ↔ sub-mm – Telescope diameter • Small 1 m ↔ large 64 m – Location • cities ↔ mountains – Run by • University laboratory ↔ NAOJ • Sometimes, there might be conflicts of interests. The 3 rd IUCAF Summer School, 3 June 2010 3

Thus we need a committee to discuss. • This is “Radio Astronomy Frequency Committee in Japan ”. The 3 rd IUCAF Summer School, 3 June 2010 4

Structure to Accomplish the Committee’s Role Steering Committee of NAOJ’s Radio Astronomy Division Japanese radio astronomers’ community NAOJ Radio Astronomy Frequency Committee in Japan LEGEND Appointment and/or steering • NAOJ is the only one observatory for common use in Japan. • It is supported by Japanese astronomers’ community. • Thus, it is appropriate to have a division to handle regulatory matters. Supply of members The 3 rd IUCAF Summer School, 3 June 2010 5

The committee • 9 members from NAOJ • 12 members from institutes other than NAOJ – Kagosima univ. , Keio Univ. , Univ. Tokyo, Univ. Hokkaido, Gifu Univ. , Yamaguchi Univ. , Waseda Univ. , Univ. Tohoku, Tokai Univ. , Univ. Nagoya, Inst. Space and Astronautical Science, Geospatial Information Authority of Japan • 3 out of 9 NAOJ members belong to the Secretary Division of the committee. The 3 rd IUCAF Summer School, 3 June 2010 6

The Secretary Division of the committee • We have secretary division of: – 1 full-time personnel – 2 part-time personnel • Costs are paid by NAOJ. • Backgrounds: – Committees are volunteer-based generally. – Committee members meet and discuss, but are not expected to work. – But we have to work every day to protect radio astronomy against industries. – The solution is to have a secretary division.

Summary • We have to have a national body for each country or region to decide and propose better regulatory ways to the regulatory authorities for radio astronomers. The 3 rd IUCAF Summer School, 3 June 2010 8
