First neutral beam experiments on Wendelstein 7-X
Nuclear Fusion, 2021 In the previous divertor campaign, the Wendelstein 7-X (W7-X) device injected 3.6 MW of neutral beam heating power allowing for the achievement of densities approaching 2 × 1020 m−3, and providing the first initial assessment of fast ion confinement in a

Computer Graphics Forum, Volume 44, Issue 3, June 2025.Abstract We introduce a fast and invertible approximation for fusion plasma simulation data represented as 2D planar meshes with connectivities approximating magnetic field lines along the toroidal dimension in deformed 3D toroidal spaces. Scientific variables (e.g., density and temperature) in these fusion data are interpolated following a complex ...

Study on resonant electron cyclotron heating by OSXB double mode conversion at the W7-X stellarator
Nuclear Engineering and Technology, 2018 Electromagnetic waves potentially have been used to heat overdense nuclear fusion plasmas through a double mode conversion from ordinary to slow extraordinary and finally to Electron Bernstein Wave (EBW) modes, OSXB.

Asteroseismological Observations of the Central Star of the Planetary Nebula NGC 1501
, 1996 We report on a global CCD time-series photometric campaign to decode the pulsations of the nucleus of the planetary nebula NGC1501. The star is hot and hydrogen-deficient, similar to the pre-white-dwarf PG 1159 stars. NGC1501 shows pulsational brightness

Validation of a synthetic fast ion loss detector model for Wendelstein 7-X
Nuclear FusionWe present the first validated synthetic diagnostic for fast ion loss detectors (FILDs) in the Wendelstein 7-X (W7-X) stellarator. This model has been developed on, and validated against experimental data from, a FILD provided by the National Institute ...

K2 Discovers a Busy Bee: An Unusual Transiting Neptune Found in the Beehive Cluster
, 2016 Open clusters have been the focus of several exoplanet surveys but only a few planets have so far been discovered. The \emph{Kepler} spacecraft revealed an abundance of small planets around small, cool stars, therefore, such cluster members are prime ...
