摘要：
A model for characterizing the cold edge component of spectra measured in charge-exchange recombination spectroscopy (CHERS) applications is presented. It provides a rapid means of constraining the amplitude and width of the cold component of spectra for which the characteristics of the hot charge-exchange emission are desired. The model utilizes the CHERS measurements themselves and measurements of the electron density near the radius of peak background emissivity. A comparison of model predictions with direct measurements of the background emission during neutral beam injection is presented. Influences of changes in background emission on the inferred ion temperature during a neutral beam pulse are discussed. © 1995 American Institute of Physics.
