Fast ion orbits in spherical tokamaks [PDF]

, 1995
In a spherical tokamak, the 1/R variation of the toroidal field is extreme, and for a given value of the safety factor a relatively low average toroidal field can be used, together with large plasma current and large plasma minor radius and elongation. The poloidal and toroidal fields are then of similar size.

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

Preparing for First Diverted Plasma Operation in the ST40 High-Field Spherical Tokamak

, 2021
The ST40 tokamak [1], built and operated by Tokamak Energy, has recently been upgraded with upper and lower divertors to enable double null diverted operations with up to 1MA of plasma current and 2MW of neutral beam heating.

Robust Bayesian inference in Iq-Spherical models [PDF]

, 1992
The class of multivariate lq-spherical distributions is introduced and defined through their isodensity surfaces. We prove that, under a Jeffreys' type improper prior on the scale parameter, posterior inference on the location parameters is the same for

Current rearrangement in merging start-up of spherical tokamak plasmas

Nuclear Fusion
Torus plasma merging technique that provides high power ion heating by magnetic reconnection is expected to significantly expand the operation scenarios of spherical tokamak (ST) fusion reactors.

Tokamak City - Hello, Kepler 62f

, 2015
A runaway factory is on its way to the earth-like planet orbiting within the habitable zone of Kepler-62, in the constellation of Lyra. The planet is known by its Kepler Object of Interest designation KOI-701.04, or simply as Kepler-62f.

First experimental realization of robust negative triangularity plasma control in a spherical tokamak

In this work, we present the experimental realization of a plasma with a steady negative triangularity in a spherical tokamak (MAST-U) for the first time.

Transient process of a spherical tokamak plasma startup by electron cyclotron waves

, 2011
Non-inductive startup by a 2.45 GHz microwave through electron cyclotron resonance heating (ECRH) has been studied in the SUNIST spherical tokamak (R/a: 0.3 m/0.23 m; B T0: < 0.15 T).
