Monochromator Positioning

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
Environment High Vacuum



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.
