Abstract
We report on the results of development, fabrication, and analysis of broadband Mo/Si multilayer mirrors for spectroheliographs at the KORTES solar observatory, which operate in the spectral bands of 17–21 and 28–33 nm. The advantages of the stack approach are demonstrated. The results of measurements of reflection characteristics of mirrors are considered.
