XRD beyond expectations
The D8 DISCOVER Plus is the most powerful and versatile X-ray diffractometer on the market.
Core is the high-accuracy ATLAS goniometer that hosts the high-efficiency Turbo X-ray source (TXS-HE) and the market-leading Non-Coplanar Arm.
It is designed for the structural characterization of the full range of materials from powders, amorphous and polycrystalline materials to epitaxial multi-layered thin films at ambient and non-ambient conditions.
Applications:
The D8 DISCOVER Plus can be equipped with the Non-Coplanar Arm to perform In-Plane diffraction measurements with unrivalled performance.
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:
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.
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.

EIGER2 R 500K
MONTEL Plus with dedicated optics
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.
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.
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.
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:
