Charge-exchange recombination spectroscopy and beam-emission spectroscopy for C-Mod

The design of two beam-based diagnostic systems for C-Mod, charge-exchange recombination spectroscopy (CXRS) and beam-emission spectroscopy (BES) will be presented. A 50-keV diagnostic neutral beam (DNB) will be installed on C-Mod for these and other diagnostics. By adding BES and CXRS to the set of...

Description
Summary:The design of two beam-based diagnostic systems for C-Mod, charge-exchange recombination spectroscopy (CXRS) and beam-emission spectroscopy (BES) will be presented. A 50-keV diagnostic neutral beam (DNB) will be installed on C-Mod for these and other diagnostics. By adding BES and CXRS to the set of C-Mod diagnostics, it will be possible to test theory-based models of turbulent transport, which are typically based on marginal stability and the existence/dominance of ion temperature gradient (ITG) modes. Tests that coordinate turbulence measurements with transport measurements are largely unavailable at present.
