Charge Exchange Recombination Spectroscopy in High Field Tokamaks

Fusion energy has been actively researched for the
last fifty years. Although, there are still many
physical and engineering problems to solve, the
international scientific community steadily moves
forward to that very sacred goal creation of
controlled nuclear fusion and its use as an ultimate
energy source for the future. This book includes a
detailed description of an optical spectroscopic
technique used for critical measurements of fusion
plasmas and of the analysis methods. A charge
exchange recombination spectroscopy diagnostic is
implemented on Alcator C-Mod tokamak to study the
high density plasma in a high magnetic field.
Density, temperature, and flow velocity of the
emitting plasma ions are derived from the analysis of
the emission spectra. The application of the
CXRS-measured temporally and spatially resolved
plasma parameters to the study of the impurity
anomalous transport and the ITB (impurity transport
barrier) turbulence suppression mechanism was
demonstrated.
