고온초전도 기기용 데이터 수집 장치의 성능 분석 = Performance Analysis of Data Acquisition Instruments for High-Temperature Superconducting Devices

다국어 초록 (Multilingual Abstract)

Selecting an optimal DAQ instrument is crucial for testing high-temperature superconducting (HTS) devices, especially for microvolt scale voltage measurement. The widely-used SCXI-1125 from National Instruments is discontinued, leading us to conduct a comprehensive analysis for an alternative. We evaluated PXIe-4300, SCXI-1125, DT9824, and PXIe-4302, comparing their performance in experiments on the critical current of RE-Ba-Cu-O composite superconducting wire and small-scale voltage. Based on test results, we identified the most suitable DAQ instrument for our research project aiming to develop an HTS D-shape toroidal magnet and high-current cable for a fusion reactor and superconducting magnetic energy storage.
