KONUS-RF EXPERIMENT FOR STUDYING HARD X-RAY AND GAMMA-RAY RADIATION OF SOLAR FLARES AND GAMMA-RAY BURSTS: FIRST RESULTS
KONUS-RF instrument is a scintillation gamma-spectrometer designed for studying the light curves, energy spectra and spectral variability of hard X-ray and gamma-ray emission of solar flares as well as cosmic gamma-ray bursts with a high-resolution in a wide energy range - 10 keV…10 MeV. The scientific program of the KONUS-RF experiment has been successfully carried out since the instrument was switched on in February, 2009. For the past period February - June, 2009 there were registered and investigated 40 gamma-ray bursts and 6 bursts from soft gamma-repeaters. A solar activity has not been noticed in the energy range - 10 keV…10 MeV during the period. Simultaneous observations by the KONUS-RF and KONUSWIND instruments onboard two spacecraft give the opportunity to obtain more detailed information on the events registered.
