Key Features
Non-Coplanar Arm
The D8 DISCOVER Plus can be equipped with the Non-Coplanar Arm to perform In-Plane diffraction measurements with unrivalled performance.
- Accessible 2θ range of up to 160° for unrivalled accuracy in d-spacing determination.
- Unmatched accuracy with direct angular encoder.
- Dedicated beam path components increase the measured intensities to obtain signals even from ultra thin polycrystalline films.
- Seamless integration in DIFFRAC.SUITE software and in DIFFRAC.DAVINCI for maximized efficiency.
ATLAS™ Goniometer
In X-ray diffraction the base for an accurate sample analysis is the goniometer and the precise orientation of the mounted components particularly while measuring. The ATLAS goniometer exactly meets these requirements by design and sets the benchmark for angular and spatial accuracy:
- Robust and maintenance-free goniometer
- High-precision stepper motors with high resolution optical encoders
- Precise and software monitored interfaces for mounting components
The D8 DISCOVER Plus equipped with the ATLAS goniometer comes with a Bruker AXS generic alignment guarantee: the angular deviation ∆2Theta of measured and certified peak positions 2Theta is ≤0.007°. This is verified by measuring the NIST certified standard SRM1976 with each individual instrument.
TXS-HE X-ray Source
Whether the key measure of an analytical X-ray tool is data quality, defined as signal-to-noise or signal-to-background, or sample throughput, one constant is that a more of signal is always an advantage.
The High Efficiency Turbo X-ray Source (TXS-HE) has been designed to boost signal while minimizing maintenance associated with rotating anode technology.
- Up to 5 times the intensity of an industrial sealed tube
- Line focus setup with unsurpassed focal spot brightness of 6 kW/mm2
- Ideal coupling with optics for maximum intensity
- Reduced beam path length to minimize air scatter

Coplanar Diffraction
In a coplanar experiment, the source and detector increase their angle relative to the sample surface resulting in a probing direction into the sample surface.
- Grazing Incidence Diffraction (GID) for surface sensitive identification of crystalline phases and determination of their structural properties including crystallite size and strain.
- X-ray reflectometry (XRR) for the extraction of thicknesses, material densities and interface structures in multi-layer samples – from simple substrates to highly complex superlattice structures.
- Grazing Incidence Small Angle X-Ray Scattering (GISAXS)
Non-Coplanar Diffraction
In a non-coplanar experiment, the source and detector angle relative to the sample surface is fixed, with the detector moving in a direction parallel to the sample surface resulting in a probing direction along the sample surface.
- In-Plane Grazing Incidence Diffraction (IPGID) reduces the penetration depth to nm, allowing surface isolation and increase sensitivity to layers with atomic thicknesses.
- Polycrystalline IPGID allows the determination of in-plane crystallite size
- Epitaxial IPGID allows direct determination of in-plane lattice parameters and in-plane orientation.
Materials Research
The ATLAS goniometer increases both the angular and real space positioning accuracy of analyses allowing large scale measurements from miniature areas of the sample. A new class of diffractometer is realized by combining the symmetric divergence IµS with MONTELPlus and multimode EIGER2 R family of detectors, resulting in beam quality and detection capability similar to that found at beamlines.
- Grazing Incidence Diffraction (GID) for surface sensitive Identification of crystalline Phases and determination of their structural properties like crystallite size and strain.
- X-ray reflectometry (XRR) for the extraction of thicknesses, material densities and interface structures in multi-layer samples – from simple substrates to highly complex superlattice structures.
- High-resolution X-ray Diffraction (HRXRD) for the analysis of epitaxial grown sample structures: Layer thickness, strain, relaxation, mosaicity, composition analysis of mixed crystals.
- Stress and Texture (preferred orientation) analysis
- Wide Angle X-ray Scattering (WAXS)
Powder Diffraction
Powder Diffraction (XRPD) covers a wide range of applications on samples with a low degree of orientation. The D8 DISCOVER Plus brings XRPD to a new level of precision with the ATLAS goniometer. By improving the accuracy beyond the industry leading D8 goniometer, XRPD analysis on the D8 DISCOVER Plus allows researchers to uncover minor structural details not previously observed. Equipping the D8 DISCOVER Plus with the TXS-HE allows acquisition of XRPD data over 5x faster than a conventional tube system.
Combined with the powerful DIFFRAC.SUITE software the D8 DISCOVER Plus enables the simple execution of PXRD application like:
- Phase Identification
- Phase Quantification
- Structure Solution
- Pair Distribution Function Analysis (PDF)
- Small Angle X-ray Scattering (SAXS)
