Detector Characterizationシステムの開発・試運転

内山、田中、端山、宮川、三代木、山本、譲原の6人で入坑 2012年10月15日~19日の5日間(前半3日で準備、3日目途中から実際のデータ取得)

1. KAGRAで使用するリアルタイム制御用DAQシステムから生成されるフレームデータの検証

2. 観測からサイエンスを引き出すため、リアルタイムに観測データの質や状態を把握するシステムの開発

CLIOの各装置モニター、周辺環境モニターを設置し、多面的にCLIOの観測状態の把握 雑音解析の結果をリアルタイムに表示 観測から期待できるサイエンスのモニター

3. キャリブレーションによって干渉計の位相の変化を時空の歪みに変換
