abstract = {The concept and structure of the Simulation of Spectra
(SOS) code is described starting with an introduction to the
physics background of the project and the development of a
simulation tool enabling the modeling of charge-exchange
recombination spectroscopy (CXRS) and associated passive
background spectra observed in hot fusion plasmas. The
generic structure of the code implies its general
applicability to any fusion device, the development is
indeed based on over two decades of spectroscopic
observations and validation of derived plasma data. Four
main types of active spectra are addressed in SOS. The first
type represents thermal low-Z impurity ions and the
associated spectral background. The second type of spectra
represent slowing-down high energy ions created from either
thermo-nuclear fusion reactions or ions from injected high
energy neutral beams. Two other modules are dedicated to
CXRS spectra representing bulk plasma ions (H+, D+, or T+)
and beam emission spectroscopy (BES) or Motional Stark
Effect (MSE) spectrum appearing in the same spectral range.
The main part of the paper describes the physics background
for the underlying emission processes: active and passive
CXRS emission, continuum radiation, edge line emission, halo
and plume effect, or finally the charge exchange (CX)
cross-section effects on line shapes. The description is
summarized by modeling the fast ions emissions, e.g., either
of the α particles of the fusion reaction or of the beam
ions itself},
