Development of radial neutral beam injection system on LHD
A radial Neutral Beam Injector (NBI) is newly installed on the Large Helical Device (LHD). The aims of the NBI are its usage as a diagnostic NB for charge exchange recombination spectroscopic measurement and using the NB as a heating source for ions in plasmas. A new positive-ion source was developed for this NBI at NIFS. The structure of the cusp field of the source was determined by the numer...
متن کاملControl and Design of a Arc Power Supply for KSTAR’s the Neutral Beam Injection
The neutral beam injection generate ultra-high temperature energy in the tokamak of nuclear fusion. The neutral beam injection make up arc power supply, filament power supply and acceleration & deceleration power supply. The arc power supply has characteristics of low voltage and high current. Arc power supply generate arc through constant output of voltage and current. So this paper proposed s...
متن کاملCommissioning Results of the KSTAR Neutral Beam System
The neutral beam injection (NBI) system is designed to provide the ion heating and current drive for the high performance operation and long pulse operation of the Korean Superconducting Tokamak Advanced Research (KSTAR). The KSTAR NBI consists of two beam lines. Each beam line contains three ion sources of which one ion source has been designed to deliver more than 2.5 MW of deuterium neutral ...
متن کاملPower Balance in Neutral Beam Heated Discharges on the National Spherical Torus Experiment (NSTX)
The understanding of power balance is an important aspect of magnetic confinement. It is particularly important to understand loss mechanisms and transport. The inherently low toroidal field of low aspect ratio machines means that much of the analysis of standard aspect ratio devices must be modified. Typically, analyses of confinement and transport in large aspect ratio devices use the approxi...
متن کاملBroad wavenumber turbulence measurements during neutral beam injection on the DIII-D Tokamak
Density fluctuation measurements covering a wavenumber range relevant to ITG, TEM and ETG type instabilities (k⊥ρi ≈ 0.2 → 10) are compared during Ohmic and neutral beam injection (NBI). These short time duration NBI perturbations modified the background temperature as well as the density fluctuation behaviour but had little effect on the background density. It is found that both the measured a...
