5 – ASDEX Upgrade

Experiments in the midsized tokamak ASDEX Upgrade (AUG) aim at improving the physics base for ITER and DEMO to prepare operation and aid the design. Being equipped with all tungsten plasma facing components ASDEX Upgrade could acquire important results concerning the fuel retention, tungsten sources and transport important for the operation of all metal devices. The availability of powerful heating systems as well as a comprehensive set of diagnostics allowed pushing the physics understanding in several areas such as pedestal and H-Mode physics, power exhaust and magneto hydro-dynamics (MHD) and development of integrated operational scenarios. Over the next 2 years the capabilities of the heating and current drive systems will be further improved, finally making available about 34 MW of auxiliary heating power. Additionally, existing diagnostic systems will be upgraded and new ones will be installed in order to provide even better insight into the physics of advanced and high power exhaust scenarios.
