Precise angular positioning for crystals, optics, and beam diagnostics
|Motion||X, Z, Theta: ATS2000 and APR150-135|
|Critical Specification||Rotary step size: 0.1 arc sec or better|
Positioning of diffraction crystals for X-ray beam monochromators in a high-vacuum environment requires the highest level of in-position stability and minimum incremental motion. The APR-150 achieves these specifications easily, and there are no other competitive mechanical bearing solutions for use in vacuum environments.
