Description
The SOHO Ultraviolet Coronagraph Spectrometer (UVCS/SOHO) is composed of three
reflecting telescopes with external and internal occultation and a spectrometer
assembly consisting of two toric grating spectrometers and a visible light
polarimeter. The purpose of the UVCS instrument is to provide a body of data
that can be used to address a broad range of scientific questions regarding the
nature of the solar corona and the generation of the solar wind. The primary
scientific goals are the following: to locate and characterize the coronal
source regions of the solar wind, to identify and understand the dominant
physical processes that accelerate the solar wind, to understand how the
coronal plasma is heated in solar wind acceleration regions, and to increase
the knowledge of coronal phenomena that control the physical properties of the
solar wind as determined by in situ measurements. To progress toward these
goals, the UVCS will perform ultraviolet spectroscopy and visible polarimetry
to be combined with plasma diagnostic analysis techniques to provide detailed
empirical descriptions of the extended solar corona from the coronal base to a
heliocentric height of 12 solar radii.
