| 内容記述 | A new database system for the JT-60SA tokamak has been developed. This system meets the following requirements: to hold all the JT-60SA data and prevent loss of data, to allow researchers to use the data without knowing internal configuration and structure of the database, to manage revision of the data so that the stored data can be traced back to an older revision at any time. Depending on timing of data transfer for storage or reference, experiment data are categorized into three types: (i) discharge data, (ii) plant monitoring data and (iii) unprocessed data. The discharge data, e.g. plasma current and plasma parameters, are acquired in a discharge sequence. The discharge data need to be referred to immediately after the plasma discharge in order to analyze the discharge and to determine operation parameters of the next discharge. The plant monitoring data are acquired continuously 24 hours a day, which represent operating status of the JT-60SA systems such as vacuum vessel temperature and pressure. The plant monitoring data might be used to monitor the status of the JT-60SA systems for a long duration irrespective of discharge sequences. The unprocessed data are raw data to be processed into physics data and primary sources of the discharge data. The unprocessed data with fast sampling frequency and/or high resolution could be used to analyze discharges more in detail after the experiments. This paper reports details about the functions of the new JT-60SA database system. Furthermore, the elapsed time for data transfer and storage was measured to evaluate the performance of the JT-60SA database system. | |||||
