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.

Diagnostics and Analysis
JJ X-Ray offers a range of cutting-edge products designed to enhance the precision and reliability of X-ray analysis systems. Diagnostic and analytic tools are essential for accurately measuring and analyzing X-ray beams, ensuring optimal performance across a variety of applications.

Positioning Systems
JJ X-Ray offers an extensive selection of positioning systems, designed for exact motion and endurance with a focus on scientific sector. Achieving groundbreaking results hinges on precise control, and our systems deliver reliable, repeatable motions for a variety of applications.

Custom Solutions
When working on complex or custom projects, we always work in close collaboration with the customer to make sure all requirements are met, and projects are executed in a timely manner.

Pink Beam Slits – 50W
Our Pink Beam slit, IB-C30-UHV-50W, is actively water-cooled through cold fingers and are fitted with copper braids as well. It can absorb a heat load of 50W. Great care has been taken to ensure that the impact of the cooling scheme on mechanical performance is neglectable. This is in particular achieved through an optimization of the thermal connections to the Cu braids that in our design, exhibits bond-like characteristics.
The cooling arrangement is implemented in such a way that the beam defining entity can be any of our available blades including; nano-polished rods, knife-edges, single crystals or multilayers. This versatility means that the IB-C30-UHV-50W is easily tailored to fit the pink beam defining needs of most beamlines at most energies.
As an additional and very convenient feature, a DN100CF Port for mounting of ion pumps is an integrated part of the design.
IB-C30-UHV-50W is an upgrade of our well-known IB-C30-UHV slit which is used at numerous x-ray facilities around the world.
