Available in PDF, EPUB and Kindle. Book excerpt: The National Spherical Torus Experiment (NSTX) Project will provide a national facility for the study of plasma confinement, heating, and current drive in a low-aspect-ratio, spherical torus (ST) configuration. The ST configuration is an alternate confinement concept which is characterized by high beta, high elongation, high bootstrap fraction, and low toroidal magnetic field compared to conventional tokamaks. The NSTX is the next-step ST experiment following smaller experiments such as the Princeton Plasma Physics Laboratory CDX-U (Current Drive Experiment-Upgrade), the START (Small Tight Aspect Ratio Tokamak) at Culham Laboratory, UK, and the HIT (Helicity Injected Tokamak) at the University of Washington, and it is smaller in scale to the MAST (Meg-Amp Spherical Tokamak) machine now under construction at Culham. This paper provides a description of the NSTX mission and gives an overview of the main engineering features of the design of the machine and facility and discusses some of the key design solutions.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the NSTX Center Stack Upgrade project is to expand the NSTX operational space and thereby the physics basis for next-step ST facilities. The plasma aspect ratio (ratio of plasma major to minor radius) of the upgrade is increased to 1.5 from the original value of 1.26, which increases the cross sectional area of the center stack by a factor of ~ 3 and makes possible higher levels of performance and pulse duration.

Book excerpt: The NSTX (National Spherical Torus Experiment) facility located at Princeton Plasma Physics Laboratory is the newest national fusion science experimental facility for the restructured US Fusion Energy Science Program. The NSTX project was approved in Fy 97 as the first proof-of-principle national fusion facility dedicated to the spherical torus research. On Feb. 15, 1999, the first plasma was achieved 10 weeks ahead of schedule. The project was completed on budget and with an outstanding safety record. This paper gives an overview of the NSTX facility construction and the initial plasma operations.

This book was released on 2009 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anomalous electron thermal transport in magnetically-confined plasma hinders efforts to achieve feasible magnetic fusion energy, and an adequate understanding of anomalous electron thermal transport remains elusive. Gyrokinetic simulations of plasma turbulence indicate electron temperature gradient (ETG) turbulence may generate experimentally-relevant electron thermal transport. To investigate ETG turbulence, a collective scattering system was installed on the National Spherical Torus Experiment (NSTX). Collective scattering provides fluctuation measurements with spatial and k-space localization, and the NSTX collective scattering system measures fluctuations on the electron gyro-scale. This Dissertation describes the design and operation of the NSTX collective scattering system and presents fluctuation measurements, gyrokinetic calculations, and transport calculations pertaining to ETG turbulence. Measurements and analysis indicate electron gyro-scale fluctuations are present in a variety of NSTX plasma regimes, and the observed fluctuations are consistent with ETG turbulence. Additional results pertain to the ETG critical gradient, flow shear suppression of ETG turbulence, ETG-driven electron thermal transport, fluctuation magnitudes, and k-spectra. The measurements can be a challenging validation test for nonlinear gyrokinetic simulations.
