Distributed Poloidal Magnetic Field Measurement in Tokamaks Using Polarization-Sensitive Reflectometric Fiber Optic Sensor [PDF]
Sensors, 2023 Determination of the poloidal magnetic field distribution in tokamaks is of prime importance for the successful operation of tokamaks. In this paper, we propose a polarization-sensitive reflectometry-based optical fiber sensor for measuring the spatial ...

A promising approach to steady-state fusion: High-temperature superconducting strong-field stellarator with precise omnigenity [PDF]
The InnovationThe stellarator has inherent advantages over the tokamak in achieving steady-state operation, especially due to its absence of disruptions and lack of need for current drive and the associated recirculating power.

On The Confinement of a Tokamak Plasma [PDF]
SIAM Journal on Mathematical Analysis, 2010 The goal of this paper is to understand from a mathematical point of view the magnetic confinement of plasmas for fusion. Following Frénod and Sonnendrücker \cite{FS2}, we first use two-scale convergence tools to derive a gyrokinetic system for a plasma submitted to a large magnetic field with a slowly spatially varying intensity.

Mid Century Carbon Free Sustainable Energy Development Based on Fusion Breeding
IEEE Access, 2018 Fusion has often been billed as the ultimate 21st century sustainable energy source. However, not only is the pace of the program glacially slow, it seems to recede further and further into the future.

Impact of β n and spectrum of n = 1 applied fields on fast ion losses in DIII-D
Nuclear Fusion, 2023 The effect of n = 1 magnetic perturbations (MPs) on prompt fast ion losses in DIII-D has been investigated using the light ion beam probe technique.

Broadening of microwave heating beams in the DIII-D tokamak by edge turbulence
Nuclear Fusion, 2023 We have demonstrated for the first time that turbulent plasma density fluctuations in the edge of the DIII-D tokamak are responsible for substantial broadening of an injected microwave beam by successful quantitative comparison between experimental ...

Exploring Experimental Isotope Scaling and Density Limit in Tokamak Transport
PlasmaAs it turns out, both isotope scaling and density limits are phenomena closely linked to fluid closure. The necessity to include ion viscosity arises for both phenomena. Thus, we have added ion viscosity to our model. The experimental isotope scaling has
