The SWICS/MASS/STICS (SMS) Instrument Package on WIND

The main purpose of the Wind spacecraft is to measure the incoming
solar wind, magnetic fields and particles, although early on it will
also observe the Earth's foreshock region. Wind, together with
Geotail, Polar, SOHO, and Cluster projects, constitute a cooperative
scientific satellite project designated the International Solar
Terrestrial Physics (ISTP) program which aims at gaining improved
understanding of the physics of solar terrestrial relations.

The SWICS/MASS/STICS (SMS) instrument package consists of measurements
from the Solar Wind Ion Composition Spectrometer (SWICS), the High
MASS Resolution Spectrometer (MASS) and the SupraThermal Ion
Composition Spectrometer (STICS) to study the following issues:
- solar abundances
- solar wind acceleration
- physical processes in the solar atmosphere
- physical properties of the lower corona
- solar wind kinetic properties
- production of suprathermal ions
- interplanetary acceleration mechanisms
- pick-up and acceleration processes of interstellar and lunar neutrals

SWICS data consists of:
- alpha velocity
- C/O abundance
- C and O ionization temperature

STICS data consists of:
- alpha velocity
- rates (counts/spin)
- proton and alpha matrix rates (counts/spin)
- He+ and O+ matrix rates (counts/spin)

SMS data are available from UMD

and from the Polar-Wind-Geotail (PWG) Data Archive
(ftp://pwgdata.gsfc.nasa.gov/pub/00readme.html) and at the NSSDC
