SPECTROSCOPIC DIAGNOSTICS OF TOKAMAKS

open access: yesLe Journal de Physique Colloques, 1988
AbstractImpurities being an important concern in tokamaks, spectroscopy plays a key role in their understanding. Techniques for the evaluation of concentrations, power losses and transport properties are surveyed, and a few developments are outlined.

Fusion Energy and Tritium Fuel Cycle: Hydrogen Isotope Separation Technologies and Sorbent Materials. [PDF]

open access: yesSmall Methods
This review surveys sorbent‐based materials for hydrogen isotope separation, a key challenge in fusion fuel processing. Different types of adsorbents are compared in terms of selectivity, kinetics, and operational practicality. Limitations of cryogenic operation and tritium compatibility are highlighted, providing guidance toward efficient, low tritium

Zonal flow screening in negative triangularity tokamaks [PDF]

open access: yes, 2022
This paper presents a comparative study of zonal flow screening in positive and negative triangularity tokamaks. Neoclassical screening sets the strength of zonal flow shear for fixed drive and damping.

The use of iron shims to reduce the toroidal field ripple in Tokamaks [PDF]

open access: yes, 1993
A study was performed to investigate the use of laminated ferromagnetic material, iron shims, to reduce the toroidal field, TF, ripple in Tokamaks. Fixed geometry shims can reduce the TF ripple and will behave linearly for Low Field Tokamaks with central

On The Confinement of a Tokamak Plasma [PDF]

open access: yesSIAM 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 [SIAM J. Math. Anal., 32 (2001), pp. 1227–1247], 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 ...

Mid Century Carbon Free Sustainable Energy Development Based on Fusion Breeding

open access: yesIEEE 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.
