Testing for Bivariate Spherical Symmetry [PDF]

An omnibus test for spherical symmetry in R2 is proposed, employing localized empirical likelihood. The thus obtained test statistic is distri- bution-free under the null hypothesis. The asymptotic null distribution is established and critical values for

The role of momentum transfer in the detachment front response to power transients for reactor scale tokamaks

Nuclear Fusion
We have investigated the response of detached plasmas to multi-ms timescale power transients using 1D simulations of the scrape-off layer on a scale and parameter range relevant for reactor-scale tokamaks, such as the Spherical Tokamak for Energy ...

High-β equilibria in tokamaks with toroidal flow

, 2016
We extend existing 2-D analytical high-β equilibrium solutions obtained by Cowley et al. [Phys. Fluids B 3, 2066 (1991)] and Hsu et al. [Phys. Plasmas 3, 266 (1996)] to the case of toroidally flowing plasma, assuming ideal magnetohydrodynamics and ...

Confinement of fusion alpha-particles and Alfven eigenmode stability in STEP

Nuclear Fusion
The Spherical Tokamak for Energy Production (STEP) programme is focused on designing and building a prototype fusion power plant that will generate approximately 1.5–1.8 GW of deuterium-tritium fusion power.

Power balance and divertor asymmetries in the Super-X divertors of MAST-U using SOLPS-ITER

Nuclear Fusion
Spherical tokamaks (STs) present unique challenges and opportunities in the area of particle and power exhaust, intensified due to their more compact sizes.

Progress in Compact Toroid Experiments [PDF]

, 2002
The term "compact toroids" as used here means spherical tokamaks, spheromaks, and field reversed configurations, but not reversed field pinches. There are about 17 compact toroid experiments under construction or operating, with approximate parameters ...

Non-inductive high-performance discharges on TCV on the path to steady state

Nuclear Fusion
An extended experimental effort is underway on the TCV tokamak to develop scenarios compatible with long-pulse operation, featuring mostly non-inductively driven current—preferably with a large fraction of bootstrap current.

Design of a low frequency, density profile reflectometer system for the MAST-U spherical tokamak [PDF]

Validated and accurate edge profiles (temperature, density, etc.) are vitally important to the Mega Ampere Spherical Tokamak Upgrade (MAST-U) divertor and confinement effort.
