Migration and balance of 13C in the stellarator Wendelstein 7-X after 13CH4 local injection into the island divertor

Nuclear Materials and Energy
A 13C tracer experiment was carried out to investigate impurity transport and migration in the stellarator Wendelstein 7-X (W7-X). About 4.0 × 1022 molecules of 13C marked methane were injected through the divertor gas injection system during plasma ...

Liquid Jetting‐Based Miniature Robotic Navigation in Confined Fluidic Spaces

Advanced Intelligent Systems, EarlyView.
We introduce a new class of liquid‐jetting‐based miniature robots (JetBots) ranging in size from mm‐to‐cm, featuring a unified approach in design, fabrication, and actuation. They demonstrate fast locomotion (30.3 cm/s), rapid steering (648.8°/s), and diverse functions, such as puncturing soft materials and unlimited cargo sampling and delivery, paving

Divertor-safe nonlinear burn control based on a SOLPS parameterized core-edge model for ITER

Nuclear Fusion
For ITER operations, the range of desirable burning-plasma regimes with high fusion power output will be restricted by various operational constraints. These constraints include the saturation of ITER’s various heating and fueling actuators such as the ...

Tritium retention characteristics of the dust in LHD after the deuterium plasma experiment

Nuclear Materials and Energy
Tritium (T) retention of the dust particles collected at ten toroidal sections of the Large Helical Device (LHD) after the 21st experimental campaign, in which deuterium (DD) plasma experiments were conducted, were evaluated by an enhanced full ...

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

Australian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

Calorimetry measurement for energy balance and energy distribution in WEST for L-mode plasmas

Nuclear Fusion
This paper presents the energy balance of 602 pulses from four different experimental campaigns for the WEST tokamak. Different magnetic configurations have been studied, with lower single null (LSN) and upper single null (USN) configuration with ...
