CODAC
Working for the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Project in offices in France or abroad, dozens of organizations (Domestic Agencies, fusion labs, contractors) use the CODAC Core System. The °ÄÃÅÁùºÏ²Ê¸ßÊÖ Organization distributes up-to-date versions and provides training and user support.
°ÄÃÅÁùºÏ²Ê¸ßÊÖÌý°ä°¿¶Ù´¡°ä (Control, Data Access and Communication) can be thought of as the brain and central nervous system of °ÄÃÅÁùºÏ²Ê¸ßÊÖ. It physically connects all plant systems using computer networks and makes sure they speak the same language. This is a very challenging task, considering that CODAC interfaces to more than 30 different plant systems which are developed and procured by the °ÄÃÅÁùºÏ²Ê¸ßÊÖ partners. These plant systems generate and exchange an estimated total number of about 1,000,000 signals.
Ensuring a consistent way of managing these plant systems is paramount for a successful operation of °ÄÃÅÁùºÏ²Ê¸ßÊÖ. In order to achieve this, the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Organization has developed a set of standards for the plant instrumentation and control (I&C) systems called the Plant System Design Handbook and suite of software called the CODAC Core System which guarantees that central control and plant systems can communicate. The underlying basis is a widely used open-source software called  (Experimental Physics and Industrial Control System) which is also used in many other big science projects.
In addition to enabling communication and integration, CODAC provides a number of other services essential to °ÄÃÅÁùºÏ²Ê¸ßÊÖ operation. These include applications for central supervision and orchestration, the plasma control system, and central data archiving. The plasma control system will ensure that an °ÄÃÅÁùºÏ²Ê¸ßÊÖ pulse is executed correctly such that the primary machine goals are achieved (500 MW of fusion power and Q>=10). During such a pulse, a tremendous amount of data is generated which will be analyzed by physicists around the world. The central archive has the challenging responsibility to first collect all the data produced by the plant systems and second make that data available to the scientific community as quickly as possible so that analysis can start.
