Two linear guides were used for horizontal translation and rough pitch adjustment. three vertical gearboxes were used for height, roll and yaw adjustments. in the vacuum, a fine flexure structure was engineered for the fine pitch adjustment with a piezo actuator. To prevent the cooling vibrations, the cooling module was seperately fixed and the heat from the mirror was conducted by Ga/In to the cooling block. Pitch angular vibration were measured by several equipments with different conditions. Results showed that the pitch angular vibration is below 40nrad without active vibration control, and below 10nrad with active vibration isolation system.
