DualSource RAPID II

The newest member of the RAPID II family is a dual source configuration that includes a Cu microfocus sealed tube and a Mo standard sealed tube. This combination was selected based on the best performance for the crystallographer: 
a microfocus Cu tube coupled with a multilayer mirror outperforms a standard Cu sealed tube system and a standard Mo sealed tube coupled with a curved graphite monochromator outperforms a microfocus Mo source with multilayer optic. Therefore, the DualSource RAPID II gives you the best of both worlds in a wavelength switchable system.


The Advantage of Large Aperture Size

The aperture of the RAPID II is large. Very large. With a 204° capture angle in the horizontal direction, this means that you are collecting much more diffraction from your crystal during an exposure. This reduces the number of images that must be collected and scaled together. Scaling is more accurate because more equivalent reflections are measured on the same image.

The Advantage of Low Noise

The large aperture and lack of electronic noise means that powder diffraction and diffuse scattering measurements are easily made, even on small samples where long exposure times are required.

The Advantage of Simplicity

The RAPID II has a simplicity of design that means it is easy to use, so you can be less concerned about letting students and new users collect data. The 1⁄4-χ goniometer is an elegant solution for covering reciprocal space and the lack of a 2θ arm means that alignment is simpler. The RAPID II is a very reliable instrument that can be repaired in the field if necessary. In contrast, electronic detectors must be returned to the factory for repair.
