Microstability physics as illuminated in the spherical tokamak

Plasma Physics and Controlled Fusion, 2005
Spherical tokamaks (STs) have attractive features for fusion, and there is considerable interest in understanding their transport properties which depend on the underlying microinstabilities. STs are capable of operation with low magnetic fields and exhibit large inhomogeneity in the toroidal magnetic field.

Quantum Iterative Methods for Solving Differential Equations with Application to Computational Fluid Dynamics

Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.
Quantum algorithms for differential equations are developed with applications in computational fluid dynamics. The methods follow an iterative simulation framework, implementing Jacobi and Gauss–Seidel schemes on quantum registers through linear combinations of unitaries.

Relation between porosity‐based and crystal‐based femtosecond laser‐induced nanogratings in oxide glasses

International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.
Abstract Femtosecond laser irradiation in glass, under controlled conditions, can induce two types of nanogratings (NG): porous nanogratings (pNG) and crystal/glass nanogratings (cNG). While most glasses exhibit only one type, binary aluminosilicate glasses have shown both types of NG.

System Studies on the Fusion-Fission Hybrid Systems and Its Fuel Cycle

Applied Sciences, 2020
This paper is devoted to applications of fusion-fission hybrid systems (FFHS) as a powerful neutron source implementing transmutation of minor actinides (MA: Np, Am, Cm) extracted from the spent nuclear fuel (SNF) of nuclear reactors.

Magneto‐Thermal Assessment of Ferrofluid Flow in Corrugated Porous Domain With Rotating Cylinder for Nuclear Systems

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This research presents a novel approach by combining magnetohydrodynamic (MHD) flow with ohmic heating to investigate the conjugate mixed convective transport of ferrofluid in a discretely heated, smooth/wavy‐walled, square‐shaped porous compartment featuring a clockwise spinning cylindrical body positioned at various locations.

Overview of ST40 results and future: expanding the physics basis of high-field spherical tokamaks

Nuclear Fusion
The goal of the ST40 programme is to explore the physics of high-field spherical tokamaks (STs), to validate empirical and theoretical models and, hence, to build confidence in predictions required to support the design of future generations of STs. ST40

The Physics of Tokamak Start-up [PDF]

, 2012
Tokamak start-up on present-day devices usually relies on inductively induced voltage from a central solenoid. In some cases inductive startup is assisted with auxiliary power from electron cyclotron radio frequency heating. ITER, the National Spherical Torus eXperiment Upgrade and JT60, now under construction, will make use of the understanding gained

Physics aspects of the Compact Ignition Tokamak [PDF]

, 1986
The Compact Ignition Tokamak (CIT) is a proposed modest-size ignition experiment designed to study the physics of alpha-particle heating. The basic concept is to achieve ignition in a modest-size minimum cost experiment by using a high plasma density to achieve the condition of ntau/sub E/ approx. 2 x 10/sup 20/ sec m/sup -3/ required for ignition.
