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.

Collimators (X-rays / Neutrons)
All collimators are based on a custom design and are divided into three categories defined by the orientation of the foils.

Control Systems
JJ X-Ray provides comprehensive PLC solutions designed to enhance the integration and functionality beamline equipment. Our expertise in motion control and programmable logic controllers (PLCs) enables us to develop tailored automation systems that meet the specific demands in terms of precision and safety of scientific instrumentation in research environments.

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.

Fixed Masks
The white beam mask can be used in the front end or as a cost effective alternative to the white beam synchrotron slit. The white beam mask consists of two Cu alloy blocks with tapered square cutouts that can be moved vertically and latteraly such that each of the blocks from one-half of the vertical and one-half of the horizontal beam definition (like two L’s opposing each other).

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.

Custom Air Slit
Sometimes, limited space around the beamlines or special requirements for aperture size makes it difficult for a standard size slit to fit into specific instrumentation. In that case, we can design and produce a customized solution which is developed from our standard slit systems – but with a rectangular housing.
Just as the classic IB-slit, the aperture is defined by four independently movable blades (2 blades for DEMI slit systems). The blades are, in turn, controlled by a high-precision guiding rail system and high-resolution stepping motors. In general, specifications and options often are very similar to our standard IB-slits.
The customer defines blade shape and material. If the slit system is for an x-ray facility, the typical blades are 2, 5, or 10 mm tungsten carbide blades – e.g., with 0.5 degrees knife-edge, R16 cylindrical edge or 90-degree rectangular edge. For neutron instrumentation, we usually use Boron Carbide.
If it is not possible to use a standard square system in your instrumentation (the most cost-effective solution), you can also check our already existing designs of rectangular slits systems here. Please contact us for more information on a particular slit system.
In our slit catalog, you can have a quick overview of the large variety of JJ slit systems.
