Slit Systems
Over the last 25 years, JJ X-Ray has designed a large portfolio of slit systems used at x-ray and neutron facilities all over the world. Our top priority is to give the customer the best solution whether they need the slit system to be standard, modified or customized.

Collimators
All collimators are based on a custom design and are divided into three categories defined by the orientation of the foils.

Optics
JJ X-Ray A/S supplies high-precision refractive and reflective optics for synchrotron applications. Their refractive optics include SCD CRLs and lenses in beryllium, aluminum, and nickel for beam focusing. Reflective optics feature customizable mirror systems suitable for UHV/XHV environments, offering options like bending, cooling, and heating for enhanced stability and performance.

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.

AT-C30-HV
AT-C30-HV is for applications where relatively large apertures (up to 30 mm x 30 mm), and highly accurate slit-scans are required. It is, therefore, an optimum solution for customers with a need for blade motions similar to those of the standard AT-F7-HV slit, who have found the 7 mm opening too small.
The slit system holds four motors that set the position and the opening of the aperture. For each dimension, one motor defines the aperture opening, and another determines the position of the aperture. Because only one motor moves during a one-dimensional scan, the AT-C30-HV is the optimum choice for high precision scans with a fixed and relatively large aperture.
The blades can be installed in two configurations, either providing a 16 mm radius or providing a knife-edge sloping at 0.5 degrees. Standard blades are polished to obtain a roughness better than 25 nm RMS.
In its basic configuration, the AT-C30-HV slit is delivered with a flange-opening and tightening bolts to allow connection with KF-40 flanges.
