The measuring modes and observations with the x-ray spectrometer array SIXA onboard spectrum-x-gamma
Abstract
The Spectrum-X-Gamma satellite is scheduled for launch in 1993, and one of the main instruments on the satellite will be the Silicon X-ray Array (SIXA). A Finnish consortium is constructing this in collaboration with Denmark and USSR. A project at the University of Helsinki is responsible for the definitions of the measurement modes available in SIXA, and planning of its scientific usage. The instrument is a 1024 channel spectrometer with 19 elements in the energy range from 0.5 to 30 keV. It is programmed to work in several modes to adjust for various observing programs and targets. The properties are described, the use of these modes are discussed, and the scientific perspectives of SIXA are reviewed.
