Slit Systems
Over the last 25 years, JJ X-Ray has designed a large portfolio of slit systems used at x-ray and neutron facilities all over the world. Our top priority is to give the customer the best solution whether they need the slit system to be standard, modified or customized.

Collimators
All collimators are based on a custom design and are divided into three categories defined by the orientation of the foils.

Optics
JJ X-Ray A/S supplies high-precision refractive and reflective optics for synchrotron applications. Their refractive optics include SCD CRLs and lenses in beryllium, aluminum, and nickel for beam focusing. Reflective optics feature customizable mirror systems suitable for UHV/XHV environments, offering options like bending, cooling, and heating for enhanced stability and performance.

Monochromators
JJ X-Ray A/S provides a range of monochromators designed for precise control of X-ray wavelengths in various research and industrial applications. Monochromators are essential for selecting specific wavelengths from an X-ray beam, improving the quality and resolution of diffraction and spectroscopy measurements.

Double Converging Collimator
Throughout the years, many types of Neutron Double Converging Collimators have been produced by JJ X-Ray. The double converging collimator is an advanced radial collimator where foils are angled both in the vertical and horizontal plane and often with very small angular foil separation.
As with our Radial Collimators, they include intermediate collimation systems over larger angular ranges and finer collimation systems over smaller angular ranges. See also examples in our collimator catalog.
Especially with our larger designs, limiting the total system weight has been at the center of our attention.

Collimator with Cryocooler
A cold head collimator option has been added to our collimator portfolio. The collimator consists of beryllium wedges in a frame of copper placed inside a vacuum vessel. The cryocooler that is positioned on the top of the vacuum vessel works as a close-cycle cryostat that will cool the beryllium wedges via its connection to the copper frame.
