Electronic logbook development for the KSTAR commissioning

摘要

During the commissioning of the KSTAR device, electronic logbook has been developed to record participant's opinions regarding experimental procedures and results. The experimental logbook, a kind of the electronic logbooks inserts principal experimental parameters by itself and gets the experimenter's comments. Since it usually takes long time to surf around raw experimental data, a summarized comment on the experimental logbook helps physicists to analyze the results. The operation logbook, the other part of electronic logbook records history about system's abnormality, including their management history. Records on the operation logbook for components provide the criteria to validate the device's stability and the basis to complement the device operation procedure. Since a large majority of readers is interested in the information on the electronic logbook, the data is manipulated to be searched and read on the web-site which is accessible by the authenticated users. The web-site also includes a formatting function to report the logbook data as a document using Java Document Object Model (DOM) and Java Simple API for XML (SAX) API. Because there were difficulties to make an action scenario on the events due to insufficient experience of tokamak operation, it was developed in parallel during the commissioning. By training operators to write comments on every detail of the experimental results and operation events, it could be more valuable data source for the next experiments.
