Measurements and controls implementation for WEST

Abstract The WEST platform consists in a major upgrade of Tore Supra towards a steady-state tungsten (W) diverted tokamak. In support of this, significant developments are performed 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. Thanks to collaboration agreements already in force, most of the developments and some hardware procurements are performed with the help of several international partners. This paper discusses the present status of developments regarding the measurements and control for the WEST project. In particular, the integration of about 50 diagnostics in ports is completed, and their in-vessel and ex-vessel installation is underway. The refurbishment of the CODAC network architecture has been completed. The development of the new acquisition units based on PXI and of the Plasma Control System (PCS) is ongoing and some units are already available. In parallel, to prepare the plasma restart, the development of plasma magnetic and kinetic controllers has been performed on simplified plant and actuator models and plasma models.
