Experiment management system-A way towards a transparent Tokamak

摘要

At TEXTOR extensive collaborations with foreign institutes have been established. For a successful collaboration, the participating scientists must be able to plan the experiment in advance. Therefore they need tools to submit and track their experiment proposals and pulse plans. During and after the experiment access to raw and evaluated data of a TEXTOR discharge is needed to analyze TEXTOR data remotely from the home labs. A goal-oriented data analysis needs in addition a various items of data not recorded with conventional data logging. This discharge specific comments and settings are stored in a logbook. At TEXTOR a logbook with different views is implemented for the scientific experiment and the machine operation, respectively. In a further development towards a TEXTOR experiment management system the information of auxiliary heating devices is stored. The electronic logbook is realized by a client/server approach which makes the access independent from the hard- and software on the client side and allows to access the data and data supplements (metadata) by any common web browsers. All information from TEXTOR is accessible for everybody via a uniform resource locator (URL). The concept of the electronic logbook, the first experience and its possibilities for data analysis will be discussed in this paper.
