Electron cyclotron resonance heating (ECRH) at the W7-AS stellarator is performed two systems of comparable heating power at 70 GHz (0.8 MW, 3 s) and 140 GHz (0.9 MW, 0.4 s). Experiments with 140 GHz open a new parameter window with high density oper

The fluorescent rod technique is a rather new and sensitive method of experimentally mapping vacuum magnetic surfaces in toroidal confinement devices. It was applied to the modular low shear W7-AS stellarator before starting plasma experiments. Magne

The plasma edge region of the W 7-AS stellarator has a complex structure due to “natural” islands. Guiding centre orbit calculations by a Monte Carlo code indicate that there are locally fixed patterns of enhanced particle flow to the wall. Power

Plasma build-up and heating of net-current-free plasmas in W VII-A was investigated by ECRH. Experiments were performed at two ECR-frequencies (28 and 70 GHz) and different heating scenarios were investigated such as first harmonic ordinary mode heat
