abstract: A new Russian space mission CORONAS-Photon (2007 launch) is under development. The project is aimed on the space investigations of active processes on the Sun in the maximum of 24th cycle of activity. The new imaging/spectroscopic XUV instrument TESIS (TEleScope / Imaging Spectrometer) is preparing for the mission in P.N. Lebedev Physical Institute. The goal of the experiment is to study the structure and the dynamics of the solar atmosphere over a broad range of heights and temperatures using full Sun XUV spectroscopic imaging. The instrument includes several telescopic and spectrogeliographic channels and covers the spectral range from 8 to 350 A. The instrument will register images of the full Sun and solar corona up to 5 radii in narrow spectral band and monochromatic lines simultaneously in several channels. The detailed description of the instrument is presented.
