Development of the Langmuir probe under q-distribution for NCST

AIP Advances
The Langmuir probe is one of the important diagnostic methods for measuring the edge plasma parameters of tokamak. A quadruple Langmuir probe (QLP) system was designed and built on the NanChang Spherical tokamak (NCST).

System modelling and identification of Mega-Amp Spherical Tokamak

, 2001
A dynamic system response model for plasma in Mega-Amp Spherical Tokamak (MAST) has been developed using RZIP. This is a linearized tokamak model. It assumes a constant plasma current distribution and axisymmetry. The plasma and conducting structures are

Collisional transport of trace impurity ions and the role of the radial electric field in spherical tokamak plasmas [PDF]

The mitigation and control of impurities, or non-fuel ions, in tokamak plasmas is vital for reducing energy losses and an understanding of impurity transport is required in order to predict the performance of present and future tokamak devices.

Intermittency in the Scrape-off Layer of the National Spherical Torus Experiment During H-mode Confinement

, 2010
A gas puff imaging diagnostic is used in the National Spherical Tokamak Experiment [M. Ono, et al., Nucl. Fusion 40, 557 (2000)] to study the edge turbulence and intermittency present during H-mode discharges.

Theoretical interpretation of frequency sweeping observations in the Mega-Amp Spherical Tokamak

, 2005
Frequency sweeping (chirping) of high frequency magnetohydrodynamic modes is widely observed in tokamak plasmas. In this paper observations of chirping in neutral-beam-heated plasmas in the Mega-Amp Spherical Tokamak (MAST) [A. Sykes, R. J. Akers, L.
