STEREO-B IMPACT SIT
Alternate name
STEREO-B IMPACT Suprathermal Ion Telescope
Description

The Suprathermal Ion Telescope (SIT) is a time-of-flight ion mass spectrometer that measures elemental composition of He-Fe ions over the 30-2000 keV/nucleon energy range. The Field of View angles are 17X44 degrees, with the 44 deg angle in the ecliptic plane, centered ~60 deg from the spacecraft-Sun line to avoid sunlight while still intercepting insignificant numbers of Parker Spiral field controlled energetic ion fluxes The telescope analyzes ions that enter through thin entrance foils and stop in a solid state detector. A time-of-flight approach for determining the composition utilizes start and stop times obtained from secondary electrons entering a microchannel plate system. The MCP and SSD areas are each 6.0 cm2. The SIT geometric factor allows study of even small interplanetary and solar enegetic particles (SEP) events.

SIT is designed to measure energetic particles produced by a wide variety of phenomena, including particles accelerated by CME driven shocks in the solar corona and in interplanetary space, solar flares, and corotating interaction regions (CIRS). Because the shocks associated with CMEs are often quite weak at 1 AU, the energy spectra produced by these shocks are usually soft and do not extend into the MeV energy range. The large geometric factor (0.3 cm2 sr) and low energy response of SIT makes it well suited for observing energetic particles produced locally by these events.

SIT is an international project, led by Glenn Mason, Univ of Maryland with hardware contribution from the Max Planck Institute.

Solar Terrestrial Relations Observatory B
Description

The Solar-Terrestrial Relations Observatory (STEREO) mission includes two spacecraft respectively lagging (STEREO A) and leading (STEREO B) the Earth in heliocentric orbit around the Sun for remote 3-D imaging and radio observations of coronal mass ejections (CMEs). These events are responsible for large solar energetic particle events in interplanetary space and are the primary cause of major geomagnetic storms at Earth. The two spacecraft are launched to drift slowly away from the Earth in opposite directions at about 10 degrees per year for the lagging spacecraft and 20 degrees per year for the leading one. Optimal longitudinal separation of about sixty degrees is achieved after two years. Afterwards the separation gradually increases beyond the design lifetime of two years with the possibility of extended mission observations at larger angles. Science instruments selected for STEREO include the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) for extreme ultraviolet (EUV), white-light coronographic, and heliospheric imaging, the STEREO/WAVES (SWAVES) interplanetary radio burst tracker, the In situ Measurements of Particles and CME Transients (IMPACT) investigation for in-situ sampling the 3-D distribution and plasma characteristics of solar energetic particles and the interplanetary magnetic field, and the PLAsma and SupraThermal Ion and Composition (PLASTIC) experiment to measure elemental and charge composition of ambient and CME plasma ions. STEREO data recorded and stored onboard each spacecraft will be downlinked through the NASA Deep Space Network on a daily schedule. Real-time space weather data will be continuously transmitted through a separate beacon system to NASA and non-NASA receiving stations.
