Abstract
Remote operation and data analysis are becoming keys requirement of any fusion devices. In this framework a well conceived data management system integrated with a suite of analysis and remote tools are essential components for an efficient remote exploitation of any fusion device. The following components must be considered: data archiving data model architecture; remote data and computers access; pulse schedule, data analysis software and remote tools; remote control room specifications and security issues. Mandatory to minimize resources demands and learning time, solutions should be shared with operating and in construction fusion experiments wherever possible. This applies in particular to the data system where some solutions are emerging as de-facto standards: like for example the HDF5 data format and the MDSplus data acquisition and data access package. The definition of a device-generic Physics Data Model and a signal naming convention play also important roles in improving the ability to share solution and reducing learning time. As for the remote control room, the implementation of an Operation Request Gateway has been identify as an answer to security issues meanwhile remotely proving all the required features to effectively operate a device. Previous requirement have been analyzed for the new JT-60SA tokamak device. Remote exploitation is paramount in the JT-60SA case which is expected to be jointly operated between Japan and Europe. Due to the geographical distance of the two parties an optimal remote operation and remote data-analysis is considered as a key requirement in the development of JT-60SA. It this case the effects of network speed and delay have been also evaluated and tests have confirmed that the performance of various connection and data access methods can vary significantly depending on the technology used. For this reason a preliminary selection of connection technologies and methods has been carried out.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
