Abstract
We present a theoretical analysis of the possible optical coating for the Slit Assembly of the mission Solar-C EUVST. To achieve the highest possible heat rejection and maintain high reflectivity in a narrow band centered at 280 nm, we analyze several Al-based coating. Two of the proposed coatings, the SiO2/Al and the SiO2/[ZrO2/SiO2]^3/Al, have been produced and their reflectivity has been analyzed in a broadband spectrum from near UV to mid IR.

Gabriele Zeni is a PhD student in the PhD Course: Sciences, Technologies and Measurements for Space at the University of Padua, Italy. He is doing his PhD research at the Institute of Photonics and Nanotechnologies of the National Research Council, CNR-IFN, in Padua. The main topics of his PhD Thesis are the analysis and study of XUV spectroscopic instrumentation and components for space and laboratory application. He is involved in the Italian team responsible for the realization and calibration of the Slit Assembly of Solar-C EUVST; in particular, his job is mainly devoted to the analysis of the optical coating for the slit assembly. His other works focus on the realization of low-cost deformable grating and on the calibration of XUV spectroscopic instrumentations.
