“PROCESS”: Systems Studies of Spherical Tokamaks [PDF]
Fusion Engineering and Design, 2020 With a reduced aspect ratio, spherical tokamaks have a number of attractive features for a fusion power plant. This can be studied using systems codes, which allow for the rapid conceptual study of power plants covering everything, from the plasma through to electricity generation. In this paper, we describe models in the systems code PROCESS that have

Shielding Materials in the Compact Spherical Tokamak [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2019 Neutron shielding materials are a critical area of development for nuclear fusion technology. In the compact spherical tokamak, shielding efficiency improvements are particularly needed because of severe space constraints. The most spatially restricted component is the central column shield.

Application of linear electron Bernstein current drive models in reactor-relevant spherical tokamaks [PDF]
Nuclear Fusion, 2023 Electron Bernstein current drive (EBCD) systems in spherical tokamaks are sensitive to plasma and launch conditions, and therefore require large parametric scans to optimise their design.

Review of the NPA Diagnostic Application at Globus-M/M2
Atoms, 2023 The application of a neutral particle analyzer (NPA) diagnostic at the Globus-M/M2 spherical tokamaks is discussed. Physical principles of the diagnostic are reviewed. Two general approaches—active and passive measurements—are described.

Nonlinear degradation of O-X-B mode conversion in MAST Upgrade [PDF]
EPJ Web of Conferences, 2023 Spherical tokamaks like the MAST Upgrade device are often operated in an overdense regime. As a consequence, conventional electron cyclotron resonance heating (ECRH) and current drive (ECCD) are typically not possible.

Excitation of toroidally localized harmonics of global Alfvén eigenmodes
Nuclear Fusion, 2023 The spherical tokamak NSTX and the upgraded, higher toroidal field, NSTX-U, routinely create plasmas with large un-thermalized populations of super-Alfvénic fast ions.

Energy confinement scaling in the NCST spherical tokamak [PDF]
AIP AdvancesEnergy confinement time τE and its scaling law in the NanChang Spherical Tokamak (NCST) are investigated based on experimental data from NCST campaigns, with a focus on their dependence on plasma current (IP), toroidal magnetic field (BT), and electron ...
