D8 Family with EIGER2 R 500K

The Next Generation HPC Detector for the Most Powerful XRD Platform

The EIGER2 is an easy-to-use, multi-mode (0D/ 1D/ 2D) detector for the D8 ADVANCE and D8 DISCOVER diffractometer families.

The Hybrid Photon Counting (HPC) detector is based on the 2^nd generation of Dectris’ revolutionary synchrotron-proven EIGER technology. The large 2D area with over 500,000 pixels at 75x75µm² allows for wide coverage with fine resolution. Dual energy thresholds and a high dynamic range enable accurate measurement of weak and strong signals alike. Bruker’s complete and seamless integration of the EIGER2 in the DIFFRAC.SUITE architecture, the ergonomic design of the detector mount and dedicated accessories result in a powerful and easy-to use solution.

Users can take full advantage of the impressive detector features for a wide range of measurement methods ranging from powder diffraction to materials research applications. Not a typical jack of all trades, the EIGER2 is a master of all applications: The high dynamic range, large 1D opening and over 500,000 pixels enable absorber free measurements, ultra-fast data collection for powder diffraction or reciprocal space maps, and a large 2D coverage for SAXS, texture and microdiffraction experiments.

Key Benefits

Multimode detector

The EIGER2 is seamlessly integrated into the DIFFRAC.SUITE architecture: 0D, 1D and 2D data acquisition modes are implemented consistently with step, continuous and advanced measurement types. Best data quality is ensured by our patented algorithms that deliver distortion free 2D scanning data without smearing.

The EIGER2 supports every data collection strategy efficiently and allows users to obtain best diffraction data for every sample type:

0D mode for samples with rough surfaces, polycrystalline coatings and epitaxial thin films
1D mode for ultra-fast scans on powders, measured either in reflection (Bragg-Brentano) or in transmission geometry, as well as for reciprocal space mapping of epitaxial thin films
2D mode for small sample quantities, materials with preferred orientation or large crystallite sizes, for micro-mapping and for stress and texture analysis

Unrivaled ergonomic design

Whether you need large 2θ-coverage for fast powder diffraction snapshots or a wide γ-range for texture measurements, whether you want to capture a large part of the diffracted beam for SAXS/WAXS or need high angular resolution to separate closely spaced peaks - with the EIGER2 it takes only moments to optimize the instrument set-up.

The ingenious design of the Universal Detector Mount Plus enables tool-free changing of detector orientation and sample-to-detector distance for rapid switching between different applications, without having to compromise on data quality:

Compact and lightweight design with integrated real-time recognition of detector orientation and mounted accessories
Failsafe, alignment free rotation of the detector to optimize γ and 2θ angular coverage in seconds - the available scan types are automatically adapted to the detector orientation
Continuously variable detector position from 100 mm up to 500 mm, with automatic distance calibration on the D8 DISCOVER – balancing angular coverage and resolution has never been easier.

Dedicated optics

Panoramic, tool-free diffracted beam optics using the complete detector field of view were specifically designed for the EIGER2. The optics are magnetically mounted and equipped with real-time DAVINCI component recognition. These accessories complement the EIGER2 detection solution by minimizing parasitic scattering or other adverse effects such as smearing of the diffraction rings in 0D and 1D mode.

Available accessories include:

Panoramic filters, filtering K-beta radiation
Panoramic axial Sollers, reducing smearing and peak-asymmetry in Bragg-Brentano and Debye-Scherrer geometry
Panoramic evacuated flight tubes and beam-stops, minimizing the effects of air scattering for Small-Angle X-ray Scattering (SAXS) applications
