Description

The WEST project consists in a major upgrade of the superconducting medium size tokamak Tore Supra to minimize risks for ITER divertor procurement and operation. This modification consists in changing the present circular magnetic configuration to a divertor configuration and implementing an ITER like actively cooled Tungsten divertor. Heat load on divertor target will range from a few MW/m22 up to 20MW/m22 depending on the X point location and the heat flux decay length. To reach these goals while ensuring the protection of the machine, major changes and significant developments are on-going on the measurement systems (diagnostics); the control, data access and communication (CODAC); the plasma control system (PCS), the monitoring and protection of the first wall and modelling to prepare the restart of the plasma. This paper provides an overview of the diagnostics implemented on WEST addressing mainly wall interaction diagnostics such as visible spectroscopy and imaging diagnostics. The modification of the CODAC and communications networks consists mainly in the development of new acquisition units based on PXIe chassis and the implementation of a new real time network. The new functionalities and architecture of the WEST PCS are detailed; especially it ensures the orchestration of many subsystems such as diagnostics, actuators and allows handling asynchronous off-normal events during the plasma discharge. In correlation, the plasma discharge is now seen as a set of elementary pieces (called segments) joint together. Development of new plasma controllers: plasma shape, position and density control has been performed using control oriented modelling and simulations. Finally a specific activity devoted to ensure the wall protection will be discussed. It consists of pre-pulse modelling of heat flux deposited onto the first wall to raise warning before running the discharge, real time analysis and protection and post pulse analysis.
