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.
Heavy Load Table
JJ X-Ray develops customized heavy load lifting stages due to increasing demands of high precision positioning combined with heavy load instrumentation in neutron and x-ray facilities. The lifting motion is achieved by four high precision screw jacks. The screw jack is driven by a flexible coupling that is connected to a gearbox and a stepper motor at the center. The synchronized lifting motion of the system is achieved through two identical gearboxes connected to both ends of the stepper motor’s spindle. The heavy load lifting stages are intended for heavy load applications to lift a single and/or a combination of instruments.
Design Features:
- Extreme load capacities, ranging from 500 kg to 5000 kg load according to customer requirements
- Self-locking lead screw allowing in-position stability
- Small footprint and customizable support base according to customer requirements
- Lifting motion achieved by one stepper motor – cost-efficient
- Flexible coupling motion transmission allows efficient transmission and no wear and tear contrary to belt transmission

*The values were obtained by motion tests at 50 mm range with 500 kg load in Open Loop operation, meaning that the motor’s position is commanded to move and stop at the nominal target positions without any feedback from a position sensor. By conducting the test in Open Loop, stepper motor failures, which most likely go undetected in Closed Loop operation, are easily identified.
