Paper Abstract

The optical configurations studied for the EUV channels on board the Advanced Solar Coronal Explorer (ASCE) mission are presented. ASCE has been proposed to study fundamental physical processes as heating of coronal holes and streamers, driving of solar wind and coronal mass ejections. It comprises three EUV channels: the HEII channel for high-resolution spectroscopic measurements in the 57.3 - 64.3 nm region, the Te channel for the determination of the electron temperature by measuring the shapes of the electron-scattered wings of the coronal HI Ly(alpha) (121.6 nm) and the S/P channel for spectroscopic measurements in the regions near HI Ly(alpha) and O VI (103.2 nm) lines and for polarimetric measurements of the HI Lyman series lines, that will explore the possibility of measuring coronal magnetic fields. The possibility of using toroidal gratings or spherical varied line-space ones has been analyzed. The results of the ray-tracing simulations on the three channels will be presented in details.
