Abstract
A beam scanner has a beam deflector mounted within a hollow shield having a beam entrance aperture and a beam exit aperture. The beam exit aperture is sealed by a window through which the deflected beam exits the hollow shield. A spin motor rotates the hollow shield, beam deflector and the window about a spin axis. A hydraulic system maintains the periphery of the window in an undistorted condition.
