Real-time steerable frequency-stepped Doppler Backscattering (DBS) System for local helicon wave electric field measurements on the DIII-D tokamak
S. Chowdhury, N. A. Crocker, W. A. Peebles +11
A new frequency-stepped Doppler backscattering (DBS) system has been integrated with a real-time steerable electron cyclotron heating launcher to probe local background turbulence…
ELM-free Enhanced Dα H-mode with Near Zero NBI Torque Injection in DIII-D Tokamak
T. Macwan, K. Barada, J. F. Parisi +11
Enhanced H-mode (EDA H-mode), an ELM-free H-mode regime, is explored in neutral beam heated, lower single null plasmas with near zero torque injection. This regime exhibits a…
Dependence of intrinsic rotation reversals on collisionality in MAST
J. C. Hillesheim, F. I. Parra, M. Barnes +6
Tokamak plasmas rotate even without external injection of momentum. A Doppler backscattering system installed at MAST has allowed this intrinsic rotation to be studied in Ohmic L-m…
Measurement of high-k density fluctuation wavenumber spectrum in MAST and Doppler backscattering for spherical tokamaks
J. C. Hillesheim, N. A. Crocker, W. A. Peebles +7
The high-k () wavenumber spectrum of density fluctuations has been measured for the first time in MAST [B. Lloyd et al, Nucl. Fusion 43, 1665 (…
