Motion 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.

We acknowledge that reliable control systems are essential for the optimal operation of beamline components. Our programming approach emphasizes robustness, flexibility, and ease of use, which collectively simplify the day-to-day management of complex equipment. By meticulously designing PLC-based solutions, we help streamline system operation, reduce downtime, and improve overall reliability, allowing researchers and technicians to focus more on their scientific objectives.

Our experience in the field of motion control is central to delivering high-accuracy, synchronized movements critical for beamline applications. Through sophisticated PLC programming, we can coordinate multiple axes, manage feedback loops, and implement safety interlocks. This precise control ensures that delicate components are moved smoothly and accurately, minimizing potential disturbances to experimental results. The result is a system that not only performs efficiently but also maintains the integrity of sensitive experiments.

Components for the APS upgrade project

When working on complex or high value projects, we always work in close collaboration with the customer to make sure all requirements are met.

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.

The APS is one of the most technologically complex machines in the world. 
This premier national research facility provides ultra-bright, high-energy x-ray beams to more than 5,000 (and growing) scientists from across the United States.
