Scientific goals

• Dynamics of active Sun from high resolution X and XUV spectral images in the 1,85-304 Å band
• Dynamics of non-stationary solar events - flares, jets, CME in time scale from ~1 sec to months
• Diagnostics of fine structure of solar plasma in flares, active regions, coronal holes with T = 0,05-50 MK
• Study of Fe- and He-ions distribution in solar disk and corona up to 5 R_sun
