Design of a {O}94 cm mirror mount for the Petawatt Project on Nova

Technical Report ·
DOI:https://doi.org/10.2172/188633· OSTI ID:188633

The authors have designed a large optical gimbal mount that will be used on the Petawatt Project currently under construction on the Nova laser. These mounts are designed to hold and tilt {O}94 cm mirrors and gratings that will redirect the {O}60 cm beam through the Petawatt vacuum compressor. Lacking the commercial availability to house this size optic, they have engineered a large mirror mount with a high natural frequency (42 Hz), low self-weight deflection of the mirror (< {lambda}/46), and high positioning accuracy characteristics (< 1 {micro}rad using flexures and stepping motors). Analysis details and methodology are presented.
