Projects

The ASDEX Upgrade divertor tokamak (Axially Symmetric Divertor EXperiment) went into operation at Garching in 1990. At present, it is Germany's largest fusion device.

The aim of the ASDEX Upgrade programme is to prepare the physics base for ITER and DEMO. Significant progress has been made in the operation with tungsten-clad walls, understanding of transport and impurity control, ELM mitigation by frequency control, and control of performance limiting instabilities. The improved H-mode (ITER "hybrid") operation was consolidated and extends beyond the ITER baseline specifications for nTτ and the pulse length.
