Pellet-Size Scaling of Quasi-Steady-State Plasma Performance in Wendelstein 7-X
Keisuke Fujii, Edgardo Villalobos Granados, Maryam Huck +11
A continuous cryogenic-pellet injector has been used to realize long-pulse high-performance plasmas in Wendelstein 7-X (W7-X). A hydrogen ice pellet deposits particles directly in…
The Realization of a Gas Puff Imaging System on the Wendelstein 7-X Stellarator
J. L. Terry, A. von Stechow, S. G. Baek +10
A system for studying the spatio-temporal dynamics of fluctuations in the boundary of the W7-X plasma using the Gas-Puff Imaging (GPI) technique has been designed, constructed, ins…
Prevention of core particle depletion in stellarators by turbulence
H. Thienpondt, J. M. García-Regaña, I. Calvo +11
In reactor-relevant plasmas, neoclassical transport drives an outward particle flux in the core of large stellarators and predicts strongly hollow density profiles. However, this t…
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…
Heat and particle flux detachment with stable plasma conditions in the Wendelstein 7-X stellarator fusion experiment
Marcin Jakubowski, Ralf König, Oliver Schmitz +30
Reduction of particle and heat fluxes to plasma facing components is critical to achieve stable conditions for both the plasma and the plasma material interface in magnetic confine…
Compensation of phase drifts caused by ambient humidity, temperature and pressure changes for continuously operating interferometers
K. J. Brunner, J. Knauer, J. Meineke +5
Fusion experiments rely heavily on the measurement of the line-integrated electron density by interferometry for density feed-back control. In recent years the discharge length has…
