Neutral Beam Coupling with Plasma in a Compact Fusion Neutron Source
Applied Sciences, 2022 FNS-ST is a fusion neutron source project based on a spherical tokamak (R/a = 0.5 m/0.3 m) with a steady-state neutron generation of ~1018 n/s. Neutral beam injection (NBI) is supposed to maintain steady-state operation, non-inductive current drive and ...

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 ...

Ideal MHD stability of a spherical tokamak power plant and a component test facility
, 2016 We have investigated ideal MHD stability of two advanced spherical tokamak confinement concepts: the spherical tokamak power plant (STPP), a 3GW concept fusion power plasma producing 1GW of electric power, and the component test facility (CTF), a ...

Indoor UAV for Nuclear Investigation: Experimental Qualification and Field Feedback
Journal of Field Robotics, EarlyView.ABSTRACT Indoor Unmanned Aerial Vehicles (UAVs) have recently gained interest for inspection and investigation tasks in hazardous environments. In the nuclear field, indoor UAVs offer promising capabilities to reduce workers' exposure to ionizing radiation while accessing confined or elevated areas.

The optimisation of the STEP electron cyclotron current drive concept
Nuclear FusionA fusion reactor based on the spherical tokamak is very likely to be completely non-inductive for the majority of the plasma ramp-up and steady-state phases, due to the limitations imposed on the central coil assemblies by the compact design.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract We study the development of the Kelvin‐Helmholtz instability (KHI) along the dusk dayside Earth's magnetopause with and without the presence of enhanced plasma density at the shear interface. Using three‐dimensional MAGE global simulations, we establish general KHI growth rate diagrams, which depend sensitively on the transverse profiles of ...

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.Abstract Weather and climate models rely on parameterizations to represent unresolved sub‐grid processes. Traditional schemes rely on fixed coefficients that are weakly constrained and tuned offline, contributing to persistent biases that limit their ability to adapt to underlying physics.

Modelling for JET Vertical Stabilization System [PDF]
, 2010 Nuclear fusion is, in a sense, the opposite of nuclear fission. Fission, which is a mature technology, produces energy through the splitting of heavy atoms like uranium in controlled chain reactions.
