Superconducting Materials and Applications

Abstract Experimental Advanced Superconducting Tokamak (EAST) is the first whole superconducting tokamak with divertor configuration in the world [3]. Vacuum system is one of the most important sub-systems of Tokmak device. Therefore, a stable and reliable control system for vacuum operation is required essentially during the plasma discharges. The vacuum control system (VCS) was built preliminarily in 2006. As the new requirements for the vacuum operation is proposed, it is developed and expanded continually. At present the control system has consisted of gas sub-system, pump sub-system, measurement sub-system, wall conditioning sub-system, operator workstation, monitor workstation, database and web publish platform. Comparing to the preliminary one, the whole VCS have been restored and expanded except for reserving the PLCs hardware on the basic level. This paper will present the improvement on the VCS of 2006 and the advantages of the upgrade version, Meanwhile, the new techniques of AJAX (Asynchronous JavaScript and XML) and SVG (Scalable Vector Graphics) will be introduced, which is applied to the user interface at the first time.
