Product Release – Mirror Systems

JJ X-Ray mirror systems are offered both as UHV and XHV compatible with a high focus on thermal and mechanical stability. The base design is highly customizable and can be adapted to most specifications. Tailored bending (one-, two- or multi-actuated), cooling, and heating solutions are offered.

For more information see the product description on our website or contact us.

We welcome three more engineers to our team

Due to the increasing demand for custom solutions, we have hired three more development engineers during the past months, to our international engineering team.

As a growing company, we are always interested in hearing from highly talented people who would like to contribute to – and take part in our success. Feel free to send us an unsolicited application along with your CV.

3D Collimators

Due to the rising development of advanced 3D printing technology, some of our future collimators will be produced with this new method. It will be interesting when a honeycomb structure is a preference for the experimental setup. Right now, we are busy with R&D projects so we can meet our customer’s requests in this field as well.

Diamond lenses now available

After comprehensive research and development, our Single Crystal Diamond Compound Refractive Lenses are finally released! Excellent for white beam applications.

JJ X-Ray and the Danish Technical University have over the last two years been developing Compound Refractive Lenses (CRL) of Single Crystal Diamonds (SCD´s) and we will continue the development in the foreseeable future. You can read more about our lenses in our product section.

Seminar on Diamond Lenses

Christian Mammen, CEO of JJ X-Ray, will present our latest product development: A diamond refractive lens for use in CRL systems.

He will present the diamond at a seminar at Argonne National Laboratory on October 2 at 1:30 PM. For more information, please see the abstract.

Please contact Christian Mammen directly to set up a meeting during his one week visit.

Inauguration of European XFEL

By the end of 2012, JJ X-Ray initiated the development of the FXE Beamline (“Femtosecond X-ray Experiments”). The project is developed in close cooperation with the Technical University of Denmark and the European XFEL. This instrumentation aims to provide time-resolved investigations of solids, liquids, and gases. The FXE Beamline is one out of six beamlines for the fastest x-ray instrumentation in the world – the European X-ray Free Electron Laser (European XFEL).

See also our poster with FXE instrumentation or an overview of the beamline components.

JJ X-Ray in new and larger facilities

April 2016, we moved from our old facilities in Lyngby to larger premises in Hoersholm. The new buildings are still a part of the Science and Technology Park, DTU Science Park, which has close connections to the Technical University of Denmark. The location allows us to continuously benefit from the activities conducted by research groups at the Technical University of Denmark and the University of Copenhagen. Our premises are also relatively close to the MAX-lab Synchrotron and the upcoming ESS in Lund, Sweden as well as DESY and the European XFEL in Hamburg, Germany


Testing of single crystal blades

J X-Ray has been testing single crystal blades at Petra III, P10, with excellent results. Single crystal blades are part of our selection of accessories for the JJ X-Ray slit systems. Our most sold versions are 2 mm blades with Gallium Arsenide, Silicon, and Indium Phospate. Please contact for further information on this issue.

JJ X-Ray wins contract for FXE Beamline, XFEL

By the end of 2012, JJ X-Ray won the biggest contract in the history of the company together with the Technical University of Denmark: For the fastest x-ray instrumentation in the world – the European X-ray Free Electron Laser (European XFEL) – JJ X-ray will be developing, producing and implementing one out of six beamlines. The instrumentation facility is expected to be up and running by 2017.
