EIGER2 R CdTe for Laboratories
EIGER2 R CdTe hybrid-photon-counting detectors bring direct detection with high quantum efficiency for any radiation from Cu to In and enable fast and accurate data collection.
Superior count-rate performance
DECTRIS HPC detectors are designed to match the high count-rate requirements of synchrotron sources, but on the other hand, even the most advanced laboratory sources offer lower flux and brightness than a typical synchrotron beamline does. Therefore, EIGER2 R detectors far exceed the count-rate requirements of any laboratory setup and experiment. At the same time, EIGER2 R overcomes the saturation issues and limited dynamic range that are typical of integrating de- tectors, even modern ones. Thanks to its superior count-rate performance, EIGER2 R is the best match for state-of-the-art laboratory sources. It provides high accuracy for strong intensities, without saturation issues, and even allows for measurement of a direct beam.
Highest dynamic range
EIGER2 R’s zero detector background, superior count rates, and simultaneous read/write provide the highest dynamic range. Determine the highest and lowest intensities accurately and in a single image, whether you are measuring strong and weak reflections or diffuse scattering, or facing a challenging SAXS/ WAXS measurement.
Background suppression
The dual-energy discrimination of EIGER2 R enables suppression of both low- and high-energy background. A single energy-discriminating threshold, as implemented in any HPC detector, allows for the suppression of low-energy background. This is a tremendous advantage when dealing with X-ray fluorescence from the sample or low-energy contamination in the spectrum of the X-ray beam. However, with a second energy-discriminating threshold, as implemented in EIGER2, it is possible to suppress high-energy background as well. Cosmic radiation is a source of high-energy background that compromises data quality when measuring very weak signals with long exposure times. EIGER2 R achieves a fivefold reduction of high-energy background from cosmic radiation, which ensures better data quality. If there is high-energy contamination of the X-ray beam, such as higher-order harmonics, dual-energy discrimination becomes even more critical. Thanks to their lack of detector background and their extensive capabilities for suppression of experimental background with dual-energy discrimination, EIGER2 R detectors are your best choice for measuring weak intensities with high accuracy.
