ngVLA-J Development Days 2021 (Virtual: July 15-16, 2021)

Background

国立天文台では2019年度に「国立天文台ngVLA検討グループ」を組織し、ngVLAの開発・建設・運用に対する日本からの貢献の可能性を米国国立電波天文台(NRAO)とともに検討・計画してまいりました。この2年間で、ngVLA検討グループではNRAOをはじめとする国際パートナー候補との協議を進め、国立天文台先端技術センターやアルマプロジェクトがアルマの建設期および運用で得たノウハウをもとに、初期開発検討を開始しました。本ワークショップでは、ngVLAの技術コンセプトを日本のコミュニティの皆様と共有し、この2年間の技術的な進捗状況および成果を報告します。それにより、国立天文台と日本のコミュニティとの共同研究・開発の可能性を模索し、開発のアイデアを集めることを目的とします。本ワークショップは、フロントエンド、低温技術、時間・周波数伝送技術、機械設計および製造、コンピューティングに関する技術を議論の対象とします。関連する開発、共同研究、技術的アイデア等に関する発表をコミュニティの皆様から募集いたします。 ngVLAの技術コンセプトの詳細は ngVLAリファレンスデザインOpen in new windowをご参照ください。

NAOJ established the NAOJ ngVLA Study Group in FY2019 to consider and plan with NRAO a possible contribution from Japan to the development, construction and operations of ngVLA. In these initial 2 years, the Study Group has progressed in the discussion with NRAO and other prospective international partners and started some initial development studies based on the know-how acquired by ATC and the ALMA Project during the construction and operations of ALMA. In this occasion, the NAOJ ngVLA Study Group would like to share the technical concept of ngVLA with the Japanese Community and report on the progress and technical achievements in these 2 years. This will provide the framework to explore possible collaboration between NAOJ and the Community, and to gather additional development ideas. The workshop will cover topics related to frontend, cryogenics, time/freq distribution, fabrication and mechanical design, and computing. Contributions in terms of related development, collaboration interest, or additional ideas are requested from the Community. For reference, the full technical concept of ngVLA can be found in the ngVLA reference design website by NRAO.Open in new window
