  skos:definition """The Solar Wind and Suprathermal Ion Composition Studies (SWICS/MASS/STICS)
experiment on WIND comprises three major instruments: Solar Wind Ion
Composition Spectrometer (SWICS), High Mass Resolution Spectrometer (MASS), and
Suprathermal Ion Composition Spectrometer (STICS). This experiment will
determine the abundance, composition and differential energy spectra of solar
wind ions, and the composition, charge state and 3-D distribution functions of
suprathermal ions. These ions and their abundance fluctuations provide
information about events on the solar surface and the formation of the solar
wind, complementing the EPACT and 3D-PLASMA investigations.
The SMS experiment consists of five separate packages mounted on the spacecraft
body. SWICS uses electrostatic deflection, post-acceleration, and a
time-of-flight vs. energy measurement to determine the energy and elemental
charge state composition of solar wind ions.
MASS uses energy/charge analysis followed by a time of flight measurement, to
determine solar-wind ion composition with high mass-resolution (M/delta M >
100), for the first time.
STICS, similar to SWICS but not using post-acceleration, has a large geometric
factor and wide angle viewing for studies of suprathermal ions.

The SMS data processing unit and STICS analog electronics unit are mounted
separately.
