DECTRIS EIGER2® X/XE CdTe photon-counting detectors provide high quantum efficiency for hard X-ray energies up to 100 keV, with a spatial resolution of 75 µm. Their cadmium-telluride sensor, which is 750 µm thick, brings all the advantages of EIGER2 X-ray detectors to high-energy applications. A high frame rate up to 2,000 kHz; under 100 ns of effective dead time between exposures; and ideal counting statistics enabled by a sharp, single-pixel point-spread function guarantee outstanding performance and accurate data collection. 

Furthermore, these beamline detectors offer two independent energy thresholds that will enable you to suppress fluorescence background (with the lower threshold) while measuring the contribution of higher harmonics (with the upper threshold).

EIGER2 X/XE CdTe detectors come in different geometries and performances, and with optional vacuum capability. DECTRIS’ dedicated Support and Commissioning team will help you minimize any downtime.

  • Fast: these detectors offer image frame rates up to 2 kHz, along with advanced gating/triggering capabilities.
  • More & better data: our detectors feature high quantum efficiency, two adjustable energy-discriminating thresholds, and a high count rate. There is no readout noise or dark current.
  • Reliable: these detectors feature extremely stable performance and radiation hard design. Delivery terms are guaranteed, thanks to streamlined industrial production and top-notch support over the product’s entire lifetime.

Case Study

In macromolecular crystallography (MX), the increase of X-ray energy beyond the conventional 10-15 keV range promises a lot of gains: it can improve the diffraction efficiency, delivering more and better data from fewer crystals. However, up until now, the only limiting factor was hardware. 

Using an EIGER2 cadmium-telluride detector for the first time, Selina L.S. Storm, Danny Axford, and Robin L. Owen from the Diamond Light Source (DLS) showcase the benefits of higher X-ray energies for macromolecular crystallography.
