Kick-off the KAGRA GND meeting
- 2020/03/05(Thu.) 13:00-14:00(JST)
- Kickoff meeting meeting (Japanese, English)
Web meeting with Zoom2 (Zoom2)
Topics of this meeting
- Yokozawa will explain about the purpose and plan as a overview
- Yokozawa will pick up the information from the technician about KAGRA GND plan
- Pick up the opinion from listed subsystem
- I don't ask to each member to prepare the slide for this meeting
- But if you prepared something, I'm very happy
- I'm not plan to decide something and to discuss very detail. Recognition and list up the problems are important.
- After this meeting, I will start the negotiation to corresponding people.
- 横澤が目的とプランをオーバービューとして説明します。
- 横澤が技官さんから情報を集めて、現状のGNDとどのようにして設置するべきなのかの情報を集めておきます。
- 関係しそうな部分に関して意見を収集します。
- このミーティングに向けて誰かにスライドを用意してもらうことはあまり考えて居りません。
- ただ、何かのたたき台を用意してくださると嬉しいです。
- このミーティングで何かを決定したり、詳細な議論を行うことは考えて居りません。問題点の認識とリストアップに重きをおきます。
- このミーティング後に各方面へどのようにするべきかの交渉を始めようと思っております。
