The Solid Attenuator Assembly was originally designed to precisely attenuate the XFEL beam intensity in several different circumstances: In cases where the full intensity would be harmful, or would create thermal distortions on downstream x-ray optical devices, and to adjust the beam intensity delivered to the sample for fluence or intensity-dependent experiments.

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.
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.
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.
Single crystal diamond lenses are claiming an increasing share of the market for synchrotron optics. Especially for applications with high energies and where coherence preservation is important, their high thermal stability and conductivity as well as their low background scattering have been proven to be important assets.
At JJ X-Ray, we have a long history of designing and producing various types of beamline components as well as complete solutions for our customers.
A typical beamline consists of different types of optics, monochromators, attenuators, beam diagnostics, and beam defining slits. For a beamline solution, these diverse types of components need to be intelligently designed and integrated to provide the optimal x-ray or neutron beam for your desired experiment.
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).
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.
The precision and accuracy with which X-ray focusing mirrors are positioned are crucial to all experiments on the beamline. The mirror positioning system needs to reflect the relevant photon beam from the storage ring without the interference of vibrations from the environment. Selection of the desired beam redirection requires submicron size linear translations as well as pitch, roll and yaw motions in the microradian range.
A transfocator is a versatile X-ray optical device that uses compound refractive lenses (CRLs) to focus or collimate X-ray beams. By inserting different combinations of lens cartridges into the beam path, the total number of lenses—and thus the focal length—can be precisely controlled. This allows quick adjustment for different beam energies, spot sizes, and working distances. Designed for use in air or vacuum, transfocators are ideal for synchrotron and laboratory applications, offering stable, compact, and tunable X-ray beam focusing.
Positioning Systems (X-rays / Neutrons)
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.

Components for the APS upgrade project
A recent project, which is a good example for this collaboration, is the production of components for the APS-Upgrade. For this meticulously planned upgrade of the Advanced Photon Source in the US, we provide components with a total value of over 6 million USD.
The scope of supply includes 19 Compound Refractive Lens (CRL) systems, positioning equipment for long range, heavy weight, and highly precise and stabile motions. Moreover, a large number of slits, masks, filters and beam diagnostics are delivered.
One of the highlights of the supply is the new Small-Angle X-ray Scattering flight tube — one of the first major new components to be installed on a feature beamline. This system includes an integrated vacuum flight path and detector motion system. The flight path allows sample-to-detector distances ranging from 3601 mm to 11500 mm using a collapsing series of bellows. Furthermore, there is a 5-degree horizontal motion based on air casters.
