大強度陽子加速器施設(J-PARC)物質・生命科学実験施設(MLF)のような大型実験施設の実験装置は多くの研究者(ユーザー)の多種多様な実験を遂行できなければならない。このため、MLFでは中性子実験のための検出器、光学機器、計算環境、試料環境が開発、運用されている。計算環境においては、ユーザーの実験制御のために共通の装置制御ソフトウェアフレームワーク「IROHA2」を開発し、実験装置に導入している。本発表では、J-PARC MLFで計画している大強度ビーム運転に備えてIROHA2に実装された、柔軟な自動測定ユーザーインターフェース機能、外部ユーザー持込機器の実験装置制御系への簡便な組込機能、実時間データ処理機能について詳細を示す。

The instruments in a common facility for public utilization by researchers must be supported many kinds of experiments. For this purpose, neutron and muon devices and computational and sample environments have been developed and used at the instruments in Materials and Life science experimental Facility (MLF), Japan Proton Accelerator Research Complex (J-PARC). We have introduced the common instrument control software framework "IROHA2" to the neutron and muon instruments in MLF. IROHA2 consists of several severs, which are the device control, the instrument management, the sequence management and the integrate control. Users cooperate to use these servers to carry out their experiments with a web browser. Because the proton beam power injected to MLF was increased, a measurement time is shorten, it is required more automatic and flexible measurements and quick-response data processing. In addition, many outer users perform diverse experiments with their own devices in MLF.
