Abstract: | We successfully developed a new process for making strong smooth thick SiO2 films on hemispherical Kovar mandrels of various sizes designed for multishell laser fusion targets. The surface finish obtainable with a SiO2 coating 13 μm thick on a mandrel 260 μm in diameter is approximately 30 nm peak to peak, with a few defects approximately 0.3 μm deep. The r.f. magnetron sputtered SiO2 films were dense and crystalline. |
