Long-wavelength turbulence characteristics, dynamics and flows in tokamak plasmas

Date: 
Monday 19th July 2010 - 14:30 to 15:00
Venue: 
INI Seminar Room 1
Session Title: 
Plasma fluctuations (DIIID measurements)
Abstract: 
Plasma turbulence, driven by temperature and density gradients inherent to magnetically confined plasmas, drives cross-field transport of particles, energy and momentum. The basic characteristics of density turbulence in a tokamak plasma are presented along with their scaling behavior with respect to certain dimensionless variables (e.g., rho_i/a, ion gyroradius normalized to plasma radius). These turbulence features presented are experimentally measured with a spectroscopic diagnostic, Beam Emission Spectroscopy (BES), that measures localized, long-wavelength (k_perp*rho_i
