Beam emission spectroscopy measures electron density from the Doppler-shifted light emission of a heating beam excited by beam-plasma particle collisions [1]. From the measured light intensity one can calculate the electron density after proper calibration. If sufficient light is available, this technique enables us the study of electron density fluctuations and their spatial distribution via t...

The Tokamak Physics Experiment (TPX) was a steady-state, tokamak to be built at the Princeton Plasma Physics Laboratory. It would have been the first tokamak in the world with an entirely superconducting magnet system. The project was terminated by the United States Congress in 1995. However, most of the TPX mission has been adopted recently by the South Korean project KSTAR (Korean Superconduc...

A complete software suite for integrated tokamak plasma control has been developed within the DIII-D program. The suite consists of software for real-time control of all aspects of the plasma, modeling, simulation and design tools for analysis and development of controllers, a flexible and modular architecture for implementation and testing of algorithms and many fully validated models. Many el...

Large-area RF-driven ion source is being developed at Germany for the heating and current drive of ITER device [1, 2]. Negative hydrogen ion sources are major components of neutral beam injection systems in future large-scale fusion experiments such as ITER and DEMO. RF sources for the production of positive hydrogen ions have been successfully developed at IPP (Max-Planck-Institute for Plasma ...

The Korea Superconducting Tokamak Advanced Research (KSTAR) Project is the major effort of the Korean National Fusion Program (KNFP) to develop a steady-state-capable advanced superconducting tokamak to establish a scientific and technological basis for an attractive fusion reactor. Major parameters of the tokamak are: major radius 1.8 m, minor radius 0.5 m, toroidal field 3.5 Tesla, and plasma...

This work demonstrates the application of an electronic nose (e-nose) for discrimination between authentic and adulterated honey. The developed e-nose is based on electrodes covered with ionogel (ionic liquid + gelatin Fe3O4 nanoparticle) films. Authentic honey samples were submitted to analysis, capacity sensors was evaluated using principal component analysis (PCA) average relative response d...

Labyrinth weirs are utilized to transport a greater discharge during floods in contrast conventional due their increased weir crest length. Nevertheless, the geometric complexity of labyrinth weirs, determination accurate coefficients and accordingly, head-discharge ratings quite essential issues practical application. Hence, as first step present study proposes following eight standalone algor...
