ST40: Advancing the Physics Basis of Spherical Tokamak Reactors

2022
ST40 is a high field Spherical Tokamak, built and operated by Tokamak Energy, with R geo ≈0.4-0.5m, A≈1.6-1.9, κ<1.7, I p ≈0.4-0.8MA and B T ≈0.8-2.2T. Two co-injected hydrogen neutral beams deliver 0.8MW at 50kV and 0.7MW at 24kV. With deuterium the corresponding figures are 1.0MW/55kV and 0.8MW/24kV, respectively.

Soft x-ray tomography on the high field spherical tokamak ST40

Review of Scientific Instruments
As part of its roadmap to developing commercial fusion plants, Tokamak Energy Ltd. operates the high field spherical tokamak ST40. Studies on this device will help to expand the high field spherical tokamak physics basis by characterizing confinement and the fusion triple product.

Measurement of divertor surface heat flux by infra-red thermographic inversion in ST40

Review of Scientific Instruments
Diagnostic tools for understanding the edge plasma behavior in fusion devices are essential. The main focus of the present work is to present the infra-red (IR) diagnostics installed on Tokamak Energy’s spherical tokamak (ST40) and the IR thermographic inversion tool, Functional Analysis of Heat Flux (FAHF).

Integrated modeling of ST40 hot ion plasmas using the TGLF transport model

Plasma Physics and Controlled Fusion
Abstract In this paper, the turbulent transport properties of ST40 hot ion plasmas are examined and fully predictive time evolving modeling of a hot ion plasma pulse was performed. Understanding turbulent transport on spherical tokamaks (STs) is challenging due to their unique geometry characteristics.

Neutronics simulations of ST40 tokamak operations for activation foils in DD plasma operation

Journal of Instrumentation
Abstract Accurate neutron yield provides critical information on plasma performance in tokamaks. Additionally, these measurements are essential for radiation protection activities and shielding verification. This paper discusses the neutron transport simulations and presents a method for measuring the deuterium-deuterium neutron
