X-Ray Detectors for Synchrotron—EIGER2 X and XE CdTe

The EIGER2 X CdTe and EIGER2 XE CdTe X-ray detectors from Dectris Ltd have been designed for high-energy applications. These detectors combine high performance with simple integration and operation.

The detectors are fitted with a cadmium-telluride sensor, offering high quantum efficiency for hard X-ray energies of up to 100 keV. They have the added advantage of high spatial resolution, thanks to the 75 µm pixel size.

Users will not lose any photons between frames because of the dead-time-free readout. Two modifiable energy thresholds allow users to quantify the contribution of higher harmonics (the upper threshold) and differentiate fluorescence background (the lower threshold) at the same time.

With a count-rate capability of 107 photons/second/pixel and a one-pixel point spread function (PSF), the EIGER2 X and XE CdTe detectors will help users gather more accurate measurements than ever before.

This advanced X-ray detector family comprises an extensive range of detectors with active regions from 77 x 38 mm2 to 311 x 327 mm2. The XE models integrate a high frame rate with a large active area.

In addition, both versions of detectors strive for high efficiency at high energies, delivering the highest possible frame rate and resolution for next-generation synchrotrons.
