Outline of Final Research Achievements

The ALICE experiment at the LHC is now preparing for LHC Run-3 program planned to start in 2021. In this research, we developed high-throughput data acquisition and online analysis system as a key technology for the success of the upgraded ALICE experiment. To realize continuous readout scheme for the new GEM-TPC of ALICE, we built and evaluated new data acquisition system using the latest technology components (FPGA, GPU, PCI Express Gen3). Furthermore, we developed automatic control and monitoring system for large scale deployment of such a data acquisition system. We also made consideration of the possibility to apply these results and technology to future ALICE detectors and next generation high luminosity nuclear experiments such as J-PARC heavy ion experiment.

Academic Significance and Societal Importance of the Research Achievements

ALICE実験に代表される高エネルギー原子核実験では、加速器輝度の向上に伴い生成される二次粒子の粒子密度が増加し、ラピディティあたり2000に達する。そればかりでなく、近年はこのような高粒子数密度の環境下で重フレーバのような稀なプローブを低運動量まで測定することが要求される。このような条件下では、ハードウェアトリガを構築し、イベント取得頻度を抑える方式はほとんど不可能となり、代わりにトラッキングデバイスのデータをオンラインで全て取得・解析し、記録するより他ない。本研究はこのような次世代実験が抱える問題をいち早く解決するものであり、今後の実験技術にとって欠かせない基礎技術を確立したものである。
