In fusion research, the diagnostic data are obtained from different diagnostic systems, which are relatively independent (in terms of the response function, noise, calibration, etc...). The consequence is that many measurements providing the same physical quantity could provide different results. In this work, the Bayesian probability inference has been applied to the frequency modulated continuous wave reflectometry and the Far-infrared laser interferometer diagnostic systems on HL-2A tokamak, offering the integrated data analysis (IDA) for electron density profile reconstruction. With the implementation, it is demonstrated that more comprehensive inference could be delivered from IDA compared to the traditional individual data analysis technique. The data analysis program based on the Bayesian inference model has been developed to reconstruct the two-dimensional electron density profile, which permits to be further implementation of the HL-2A/2M IDA framework in the near future.

核融合研究において、診断データは異なる診断システムから取得され、それらは(応答関数、ノイズ、較正などの点で)比較的独立している。その結果、同じ物理量を提供する多くの測定が、異なる結果をもたらす可能性がある。本研究では、ベイズ確率推論をHL-2Aトカマク上の周波数変調連続波反射計および遠赤外レーザー干渉計システムに適用し、電子密度プロファイルの再構成のための統合データ解析(IDA)を提供した。この実装により、従来の個別データ解析手法と比較して、IDAからより包括的な推論が得られることが実証された。ベイズ推論モデルに基づくデータ解析プログラムを開発し、二次元電子密度プロファイルを再構成した。これにより、近い将来におけるHL-2A/2M IDAフレームワークのさらなる実装が可能となる。
