WP nr. Descriptive title Short description and specific objectives of the task 05100 Silicon Carbide prototypes Objectives: validate Silicon Carbide as a suitable substrate for segmented apertures, improve segment edge figuring techniques (eliminate the need for wasters). Tasks: fabrication/testing of 1-m SiC segments: design; fabrication process; polishable over-coatings and alternatives to diamond slurries; control of high spatial frequency misfigure 05200 Optical finishing and edge control Development of optical finishing processes for fast, cost-efficient removal of high spatial frequency misfigure on classical substrates and SiC, especially for segment edges
