Abstract
The EIT will provide wide-field images of the corona and transition region, on the solar disc and up to 1 R⊙ above the limb. Its normal incidence multilayer-coated optics will select the spectral emission lines of four ions (Fe IX, 171 Å; Fe XII, 195 Å; Fe XV, 284 Å; Hell, 304 Å), providing a sensitive temperature diagnostic in the range 6.104 to 3.106K. This SOHO instrument will thus probe the coronal plasma on a global scale, as well as the underlying cooler and turbulent atmosphere. The EIT's characteristics and performances are presented, and prospects for coordinated observations with ground-based radio observatories are outlined.
