SPECTROSCOPIC DIAGNOSTICS OF TOKAMAKS

Le 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.

Off-target gradient-driven flows in 3D simulations of ADITYA-Upgrade tokamak scrape-off layer plasma transport

Nuclear Fusion
Coupled plasma-neutral transport simulations are performed on ADITYA-Upgrade tokamak scrape-off layer (SOL) plasma, where flows in the core and SOL were measured to reverse signs with density variation.

Implementation study of cost-effective verification for Pietrzak's VDF in Ethereum smart contract

Blockchain: Research and Applications
Verifiable delay function (VDF) is a cryptographic concept that ensures a minimum delay before output through sequential processing, which is resistant to parallel computing.

Thermophysical properties and expansion anisotropy of sintered hafnium hydride compacts

Nuclear Materials and Energy
Thermophysical properties are reported on ε-HfH2 samples fabricated by powder metallurgy. Samples were heat treated in the range 300–550 °C to transform them from ε-HfH2 to δ-HfH1.6-x, allowing comparison of the properties of both phases.

CRATOS-GS: A free-boundary, hierarchical adaptive mesh refinement Grad–Shafranov solver

AIP Advances
We present CRATOS-GS, a free-boundary hierarchical adaptive mesh refinement (AMR) Grad–Shafranov solver, discretized on Cartesian meshes. The solver is suitable for stand-alone equilibrium calculations, as a foundational component of reduced modeling ...

Machine learning prediction of plasma behavior from discharge configurations on WEST

Nuclear Fusion
Accurately predicting plasma behavior based on discharge configurations is essential for the safe and efficient operation of tokamak experiments. While physics-based integrated modeling codes provide valuable insights, their high computational cost ...
