LYNXEYE detectors
The LYNXEYE Family – Highest Data Quality for Any Application
The LYNXEYE family of detectors represents the height ofperformance in compound strip detection for all X-ray diffraction andscattering applications.
The SSD160-2, LYNXEYE-2, and LYNXEYE XE-T feature advanced 500 µm silicon strip sensors, compatible with all common X-raywavelengths - from Cr to Ag - and are fully integrated with all of Bruker’s X-ray diffractometers.
The LYNXEYE HE, for the D8 ADVANCE and D8 DISCOVER, offers an air-cooled CdTe sensor optimized for applications requiring Mo or Ag radiation, like pair distribution function (PDF) analysis or operando studies on battery cells.
All LYNXEYE detectors are engineered to meet the highest standards in technicalprecision, manufacturing quality, and system/software integration - ensuring unmatched versatility, reliability, and data quality across allapplications.
Key Features
Outstanding fluorescence filtering
With an energy resolution better than 380 eV, the LYNXEYE XE-T is the highest performing detector system on the market in terms of fluorescence filtering, and the only energy dispersive detector for 0D, 1D and 2D data acquisition.
The superb energy resolution allows unprecedented filtering of fluorescence signal and K-beta radiation, delivering data with superior signal-to-noise and improved LLD/LOD. All of this is achieved without secondary beam path optics such as monochromators or metal filters, and without the resulting intensity loss.
For example, the LYNXEYE XE-T filters 100% of Fe fluorescence excited by Cu radiation and reduces Kβ radiation to <0.1% (of CuKα). The resulting data is free of unwanted scattering and artefacts, such as absorption edges from metal filters. This is critical for reliable phase identification and quantification, especially when minor phases are concerned that are often obscured by background noise.
2D scanning and BRAGG2D
A common challenge encountered during powder X-ray diffraction experiments is ensuring the specimen consists of randomly oriented crystallites with appropriate dimensions. 2D X-ray diffraction is a convenient way to visualize deviations from this ideal powder condition. It is also useful to enhance the phase-identification process by correlating line profiles and to increase quantification reliability.
All detectors of the LYNXEYE family support two ways of collecting 2D data:
On D8 ADVANCE and D8 DISCOVER diffractometers equipped with Bruker’s patented 0/90° mount, 2D data is collected in the 90° orientation using a conventional 2θ scan. With BRAGG2D, included on all diffractometers, data is measured in parafocusing beam geometry and processed with a new 2D data processing algorithm. This allows the illumination of a large specimen area with the full X-ray beam, resulting in rapid assessment of sample preparation.
Fast measurements and high dynamic range
With its high dynamic range, high count rate and fast readout times, the LYNXEYE detector family is a great choice for all applications, including materials research.
Reciprocal Space Maps (RSM) are important to characterize the structure of epitaxial multilayers and evaluate film properties – such as strain, composition and domain effects.
Using the rapidRSM™ technology, available for all LYNXEYE family detectors, RSMs are collected as a series of 1D snapshots with essentially no dead time. This dramatically reduced the required scan time to minutes or even seconds, increasing sample throughput.
For X-ray reflectometry (XRR) and high resolution XRD (HRXRD) measurements, the signal intensity varies by several orders of magnitude over the measured range. Consequently, a high dynamic range is a key detector parameter. By switching to the 90° orientation of any LYNXEYE family detector, the dynamic range increases by almost 200x, eliminating the need for absorbers – gaining speed and improving data quality.
