Accelerate Your Research

The Xeuss 3.0 is used for many applications.

Size, structure, shape, orientation…

Characterize the nanostructure of soft-matter and nanomaterials using SAXS/WAXS and USAXS technique in transmission or grazing incidence mode.

    • Particle size distribution ranging from few nanometers to more than 350 nm in diameter
    • Crystallization rates and lamellar structure of semicrystalline polymers
    • Size and shape analysis of surfactants or proteins in solutions
    • Organization and orientation of nanomaterials at atomic or nanoscale, in bulk phases or at surfaces
    • Phase segregation studies of alloys
    • In situ studies of nanostructure transitions

Maximum flexibility

Provide structural tools to a large community of users with full remote operation capability and access to a unique range of length-scales.

Advanced nanomaterials development and design require characterization over a large range of length scales. The Xeuss 3.0 offers such measuring capability over up to 5 orders in magnitude in q (wave vector) through entirely motorized change of configurations. Any trained user can thus operate the system remotely over its complete measurement range for a given sample or batch of samples.

Automatic change of measuring settings include:

    • Q-Xoom change of measurement resolution through motorized translation of detector
    • Sequential SAXS /USAXS measurement with Bonse-Hart USAXS module
    • Change of energy radiation, up to 3 energies
    • Movable WAXS detector for out of equilibrium in situ SWAXS studies
    • InXight X-ray imaging module
    • Auxiliary X-ray beam focusing channel

      Up to 3 sources modules (Cu, Mo, Cr). Can be integrated with Ga
    • MetalJet source.
    • High precision switch process enables sequential measurement on same sample with different source radiation

double source

InXight X-ray imaging module

InXight X-ray imaging module for the Xeuss 3.0 provides X-ray transmission images of the sample in synergy with scattering measurements.

It offers an automatic switch between X-ray imaging and X-ray scattering measurements to access structural information from Å to mm.

With InXight X-ray imaging module for Xeuss 3.0:

    • Rapidly collect an image of a heterogeneous sample and select regions of interest for SAXS/WAXS or USAXS measurements
    • Get a global understanding of complex samples or products by correlating local X-ray scattering and microstructure
    • Watch operando dynamics over extended length scales

AuX source module

The AuX source is an additional X-ray source option for Xeuss 3.0 providing a monochromatic beam focused on the sample. With a photon density increase by one order of magnitude compared to the main SAXS/WAXS source, it is ideal for small-spot X-ray scattering applications. The AuX source is mounted on VersaXtage allowing a quick motorized change of source configuration.

Benefits and applications of the AuX source in small-spot experiments include:

    • Improved data quality or shorter acquisition time for GIWAXS experiments and mapping
    • Capability to perform WAXS and SAXS experiments and measure particle sizes as large 50 nm
    • Access to time-resolved experiments with sub-minute time resolution

Ultimate performance

The Xeuss 3.0 offers a maximum flexibility of measurement configurations to get the best possible data quality on any type of sample.

In particular, the following key features enable the user to optimize experiments or results:


    • High flux settings adapted for fast kinetics embedded in a low background camera
    • Largest surface of detection moveable all the way from WAXS to long distance SAXS to optimize resolution and signal-to-noise
    • Long distance SAXS settings for measuring large characteristic dimensions (up to 900 nm depending on the Xeuss 3.0 model)
    • Optional USAXS module to characterize large structures ( > 2.5 µm)

Beamstopless data acquisition

SAXS acquisition continuously without any beamstop provides High Dynamic Range data.

No parasitic scattering from beamstop edges or detector window allows noise-free scattering at low q.

The direct beam is recorded simultaneously with the sample scattering profile during acquisition for accurate transmitted intensity measurement, used to obtain a precise absolute intensity normalization.

In addition, the direct beam profile thus measured is integrated in the data analysis (XSACT) to improve the accuracy of the results.

Clean Beam Technology

As a standard solution, Xeuss 3.0 integrates low maintenance microfocus beam delivery systems to provide very high flux levels previously only possible with high power rotating anode sources.
Advanced experiments such as kinetic studies or shape analysis of diluted samples can now be performed in the lab.

In addition, Xenocs X-ray beam delivery systems coupled with motorized scatterless collimation achieve high resolution (low Δq beam), which is essential for studying large characteristic dimensions or for performing accurate mesophase analysis.

The high useful flux together with the high resolution capability are achieved through the combination of:

High brightness, long lasting microfocus sources

Patented single reflection 2D multilayer optics with very high solid angle of collection

2D controlled beam size on sample and detector

To ensure the best quality of X-ray scattering measurements, including on diluted or low contrast samples, Xeuss 3.0 combines high flux with low noise technology, which is the fruit of more than 10 years of development.

Key integrated features are:

    • Fully in-vacuum system from optics to detector sensor
    • 3rd generation scatterless collimation (first introduced on the market by Xenocs in 2008)
    • In-vacuum windowless detector
    • Hybrid pixel photon counting detector
    • Proprietary automatic cosmic background reduction to reduce the impact of ambient parasitic scattering

For applications requiring very fast kinetics Xeuss 3.0 can also be delivered with a MetalJet source.

Q-Xoom with large surface of detection

The Q-Xoom features full range computer-controlled detector travel to automatically adjust the sample-to-detector distance offering maximum flexibility of measurement for experiment optimization.

The virtual detector increases the measuring capabilities offering surfaces of collection larger than 200 mm2 x 200 mm2 at any sample-to-detector distance independently of detector size with automatic data reconstruction.

The large surface of detection is beneficial to optimize the azimuthal coverage in case of anisotropic samples or to benefit from high resolution measurement settings by characterizing smaller length scales (larger wave vectors) at longer sample to detector distance by a detector offset.

Plenty of space for sample environment

With its large chamber and concept ensuring stationary sample during measurement, the Xeuss 3.0 is the perfect X-ray scattering platform instrument for now and the future.

Advanced materials research and characterization could require integration of specific or customized sample environments.

Xeuss 3.0 is perfectly adapted for such new projects thanks to its state-of-the-art beamline concept.

It provides:

  • Large vacuum chamber with stationary sample during measurement (continuous on-axis sample viewing, smart integration of customized sample environments)
  • Sample stage with long translations for sample mapping and batch measurements
  • Broad range of standard sample environments with holder recognition
