Wendelstein 7-AS was the first modular stellarator device to test some basic elements of
stellarator optimization: a reduced Shafranov shift and improved stability properties resulted …

This paper reviews the research on the reversed field pinch (RFP) in the last three decades.
Substantial experimental and theoretical progress and transformational changes have been …

Numerical results for the three mono-energetic transport coefficients required for a complete
neoclassical description of stellarator plasmas have been benchmarked within an …

Neoclassical transport is studied for large helical device (LHD) configurations in which the
magnetic axis has been shifted radially by determining the mono-energetic transport …

Abstract In the Large Helical Device (LHD), the highest operational averaged beta value has
been expanded from 3.2% to 4% in the last 2 years by increasing the heating capability and …

A low aspect ratio quasi-axisymmetric stellarator, CHS-qa, has been designed. An
optimization code has been used to design a magnetic field configuration with evaluations of …

Characteristics of MHD instabilities and their impacts on plasma confinement are studied in
current free plasmas of the Large Helical Device. Spontaneous L–H transition is often …

The partial decay width of the Z to \rmb̄b quark pairs has been measured by the DELPHI
detector at LEP using data taken in the years 1992 to 1995. Decays of b-hadrons were …

Impurity confinement in fusion plasmas is mainly determined by transport mechanisms in the
core region. For the Wendelstein 7-X stellarator, its island divertor is expected to screen …

The bounce averaged poloidal drift velocity of trapped particles in stellarators is an important
quantity in the framework of optimization of stellarators because it allows us to analyze the …
