TESIS on CORONAS-PHOTON S. V. Kuzin (XRAS) and TESIS Team TESIS: scientific tasks www.tesis.lebedev.ru Scientific tasks: Investigation of the most dynamic processes in the solar atmosphere, such as flares, coronal mass ejections, dimmings etc. Investigation of processes in far solar corona (up to 4 solar radii) in EUV Study of evolution of large-scale long-life coronal structures: active regions, coronal loops, giant arcades, coronal holes and others. Determination of the physical parameters (electron temperature and density, differential emission measure) of plasma of coronal structures. TESIS: targets of observations www.tesis.lebedev.ru Targets of observations: Solar flares – their dynamics, energy balance and physical characteristics Eruptive processes in the solar atmosphere – triggers and methods of forecasting Coronal mass ejections – their formation and dynamics Spectroscopy of coronal plasma in wide temperature range Investigation of upper Earth atmosphere TESIS INSTRUMENT OVERVIEW www.tesis.lebedev.ru Channel Aims Description Wavelength band Field of view Angular resolution MgXII Imaging Spectroheliometer (MISH) 10 MK plasma: dynamics, parameters Soft X-ray full-disk Bragg spectroheliometer with spherical bent crystal mirror MgXII 8.418 A and 8.423 A doublet 1°.15 (Full solar disk) 2 arc sec / pixel EUV Spectroheliometer (EUSH) From “cold” to “hot” plasma: parameters by means of imaging spectroscopy EUV full-disk spectroheliometer with grazing incidence diffraction grating and focusing multilayer parabolic mirror 280-330 A 1°.24 (Full solar disk compressed along dispersion) 4.4 arc sec (perpendicular to dispersion) 1.5 arc min (along dispersion) Full-disk EUV Telescopes (FET) High resolution and high cadence images of 0.05 MK and 15 MK plasma Herschelian telescopes with multilayer parabolic mirrors 130-136 A (telescope I) 290-320 A (telescope II) 1°.0 (Full solar disk) 1.7 arc sec / pixel Solar EUV Coronograph (SEC) CME structure and dynamics up to 4 solar radii Coronograph based on the RitcheyChretien scheme 290-320 A 2°.5 (inner and outer corona from 0.7 to 4 solar radii) 5 arc sec / pixel METHODS OF TESIS OBSERVATIONS www.tesis.lebedev.ru Multi-wavelength simultaneous observations of full Sun in 4 spectral channels MgXII 8.42 A FeXX 132 A TESIS will provide simultaneous imaging of the Sun in 4 spectral channels, including EUV channel 295-315 A, which allows to derive the density and the temperature composition of the plasma.
