Abstract

The study of GRB prompt emission (PE) is one of the main goals of the Lomonosovspace mission, which is being prepared at Moscow State University. The GRBmonitor (BDRG) and the wide-field optical cameras (SHOK) are intended for detection of GRBprompt emission as well as optical counterparts. The BDRG instrument consists of threeidentical NaI(Tl)/CsI(Tl) (13.0 × 2.0cm ) phoswich detectors, whose axes determine theCartesian coordinate system. This allows to localize any GRB source on the sky by means ofthe count rate seen by each detector with an accuracy of ~2 deg. The SHOKinstrument consists of two identical wide-field cameras (WFC) directed in such a way thatthe field of view (FOV) of each WFC overlaps by the corresponding BDRG FOV, which producesa trigger on the WFC in case of a GRB detection. With this setup, the GRB prompt lightcurve will be obtained in the visible without any delay with respect to gamma-rays, whichis crucial for a GRB central engine understanding.
