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.

Ultra High Precision Slits
This slit system was designed for a neutron reflectometer where the accuracy and resolution, as well as the parallelism of the slit blades, are crucial. In fact, the accuracy of the collimation provided by the slits can be directly correlated to the resolution of the experiment.
As for the other IB slits, each blade can be moved independently over the full aperture and are all fully overlapping.
The slit blade pair will remain parallel to each other and to the reference frame over the entire range of motion within 50 µrad (10’’), and the accuracy, resolution, and repeatability is < 1 µm over full range.
The slit blades for neutron reflectometers are typicall rectangular cut B4C blocks with a surface roughness Ra ̴ 0.5 µm and a straightness < 2 µm over the full length.
The aperture size can be chosen to match the specific instrument.
