TL;DR: The National Spherical Torus Experiment (NSTX) as discussed by the authors was the first experiment to establish the fusion physics principles of the spherical torus (ST) concept, and the NSTX device began plasma operations in February 1999 and the plasma current Ip was successfully brought up to the design value of 1-MA on 14 December 1999.

TL;DR: In this article, the viability of long, high bootstrap current fraction operations has been established for ELMing H mode plasmas with toroidal beta values in excess of 15% and sustained for several current relaxation times.

TL;DR: In this paper, different orbit-following codes predict the formation of a hot spot on the TBM surface arising from beam ions deposited near the edge of the plasma, and thermal analysis of the heat flow through the tiles shows that the simulated power can account for the measured tile temperature rise.

TL;DR: In this paper, six 110 GHz gyrotrons have been installed and are operational on the DIII-D tokamak, with a nominal rating of 750 kW and a 2 s pulse length, with the pulse length determined by the maximum temperature allowed on the edge cooled Boron Nitride window.
