On the lifetime of the first mirrors in the diagnostic systems of the international thermonuclear experimental reactor [PDF]

, 2006
Plasma diagnostic systems will be necessary tools for the future success of the International Thermonuclear Experimental Reactor (ITER) both to better understand the physics involved in magnetically confined burning plasma and for the protection of the

Spatial Profile of Neutral Temperature Measurement in Aditya-U Tokamak Plasmas

Atoms, 2019
The spatial profile of neutral hydrogen temperatures in Aditya-U tokamak plasma has been estimated from the spatial profile of the Hα spectral emissions measured using a high-resolution multi-track spectrometer, having a spectral resolution of 0.023

Different Types of Lithium Coating in Tokamak ADITYA

, 2012
In fusion devices, conditioning of vacuum vessel wall is important to get better plasma parameters. The impurities affect the plasma parameters such as density, temperature, and confinement time.

Implementation of an Iter-relevant Qp-based Current Limit Avoidance Algorithm in the Tcv Tokamak

The problem of avoiding saturation of the coil currents is critical in large tokamaks with superconducting coils like ITER. Indeed, if the current limits are reached, a loss of control of the plasma may lead to a major disruption.

Sawtooth stabilization by localized electron cyclotron heating in a tokamak plasma [PDF]

, 1990
Sawtooth oscillations (STO) in the ohmically heated WT-3 tokamak are strongly modified or suppressed by localized electron cyclotron resonance heating (ECH) near the q = 1 surface, where q refers to the safety factor.

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.
