Paper Abstract

Sfim ODS is involved in the French Megajoule Project managed by the Commissariat a l'Energie Atomique. It is a high power UV-laser using 240 square beams (410 mm X 410 mm). Sfim ODS achieved a technical and economical analysis concerning the production of flat-parallel debris-shields in silica (430 X 430 X 6 mm, transmitted wavefront: (lambda) /2, 2 500 shields/year) using large and specific dual-side fine- grinding and polishing machines. This analysis was supported by trials using half-scale windows (same stiffness equals> thickness equals 1.7 mm) showing the ability to reach the specifications with low production costs.
