ABSTRACT

Modeling is necessary to understand the data gathered from tex2html_wrap_inline274 and tex2html_wrap_inline276 spectroscopic diagnostics on a tokamak. The emission and transport of this radiation in Alcator C-Mod is calculated using the DEGAS 2 Monte Carlo neutral transport codegif. The plasma background needed by DEGAS 2 is obtained from a transport analysis code which takes as input measured plasma profiles. A simple model of the reflection of radiation on the walls of the device is included. By comparing the predicted spatial profiles of the emission spectra with those of the diagnostics, it is possible to infer information about the ion and neutral flows and temperatures.
