Xeuss 2.0
The SAXS/WAXS laboratory beamline

For many years, high performance SAXS measurements were limited to synchrotrons, as only such large facilities were able to simultaneously achieve high brilliance, low parasitic scattering, high resolution & versatility.

With the introduction of the Xeuss a few years ago, Xenocs made these four key parameters available to the home lab, opening the way to new SAXS/WAXS measurement capabilities.

Xenocs is now pleased to be introducing a new generation of SAXS/WAXS system : Xeuss 2.0

The Xeuss 2.0 was designed as a beamline for your own lab

It is the ouput of more than 14 years of R&D in the company and integrates all the innovative technological bricks developed by Xenocs all along these years. The Xenocs proprietary single reflection optics together with Xenocs new generation of scatterless slits generate a very intense X-ray beam with an ultra low level of parasitic signal. The Xeuss 2.0 also integrates the latest generation Pilatus detectors from Dectris for unmatched measurement capabilities.

The unique performance of the Xeuss 2.0 is enhanced by a powerful software package for system control, data acquisition & analysis. Based on SPEC from Certified Scientific Software, the Xeuss 2.0 control & data acquisition software features both easy to use graphical user interface and macro script mode for quick system access and advanced operations. The Xeuss 2.0 data processing & analysis software was developed on the basis of an exclusive partnership with Soleil synchrotron in France.

Benefitting from the experience of our customers, the Xeuss 2.0 also combines full flexibility and ergonomics. It is an open system, adaptable and upgradable to meet the needs of your application and experimental environment.

The GeniX3D microsource

Requiring only 30 W of power and producing a 30 µm spot size, the GeniX3D has a power density 10 times higher than a 1.2 kW sealed tube! This amazing technology yields higher beam intensity on the sample, higher beam stability, longer lifetime and lower cost of ownership.

The FOX3D single reflection optics

Xenocs is the only company in the world providing single reflection optics. These unique optics generate a highly collimated beam (divergence <0.4 mrad) with typically 50 % more efficiency than is produced with conventional multiple reflection optics (eg. Montel optics).

Scatterless slits 2.0

Covered by a worldwide patent, our innovative scatterless slits concept enables a factor of 10 of background reduction compared to other scatterless solution on the market.

This unique technology, not available to any other suppliers on the market, enables the Xeuss 2.0 to achieve unique qmin values down to 0.01 nm-1 and a typical signal-to-noise ratio over 9 decades leading to ultimate performance SAXS/WAXS measurements in the lab.

Xeuss 2.0 - Scatterless slits 2.0

Maximum versatility and ergonomics

The Xeuss 2.0 has been designed as an open SAXS/WAXS laboratory beamline, combining unique versatility and automation.

The system features automatic change of settings, auto-alignment, remote multiple sample measurements (allowing unattended overnight measurements, for maximum throughput).

The sample to detector distance is easily adjusted within only a few minutes, without the need for any beamstop realignment.

The Xeuss 2.0 features a large sample chamber which is set up to operate either in vacuum or in air. It can hold a large range of sample holders for transmission and grazing incidence, temperature stages, humidity cell, tensile stage, shear cells, low noise flow cell with autosampler, etc to best fit any application need. For integration of large sample environments both the sample stage and chamber may be removed to offering unique integration possibilities.
