Properties of a new quasi-axisymmetric configuration
S. A. Henneberg, M. Drevlak, C. Nührenberg +4
A novel, compact, quasi-axisymmetric configuration is presented which exhibits low fast-particle losses and is stable to ideal MHD instabilities. The design has fast-particle loss…
Electrostatic potential variation on the flux surface and its impact on impurity transport
J. M. GarcÃa-Regaña, C. D. Beidler, Y. Turkin +5
The particle transport of impurities in magnetically confined plasmas under some conditions does not find, neither quantitatively nor qualitatively, a satisfactory theory-based exp…
Design considerations of the European DEMO's IR-interferometer/polarimeter based on TRAVIS simulations
K. J. Brunner, N. Marushchenko, Y. Turkin +4
Interferometry is the primary density control diagnostic for large-scale fusion devices, including ITER and DEMO. In this paper we present a ray tracing simulation based on TRAVIS…
On neoclassical impurity transport in stellarator geometry
J. M. GarcÃa-Regaña, R. Kleiber, C. D. Beidler +3
The impurity dynamics in stellarators has become an issue of moderate concern due to the inherent tendency of the impurities to accumulate in the core when the neoclassical ambipol…
