This fall, DECTRIS is launching its EIGER2 R CdTe X-ray detector series for laboratory. Combining the best features of the Hybrid-Photon-Counting (HPC) technology and a cadmium-telluride sensor, these detectors have shown high quantum efficiency for both hard and soft radiation and a superior dynamic range. With the first results in, the new detector series of the EIGER2 family has earned its place as a new standard for laboratory equipment. 

After a successful introduction and the first deliveries of DECTRIS cadmium-telluride detectors to synchrotrons, we are thrilled to launch our EIGER2 R CdTe detector series specifically optimized for laboratory X-ray sources. At a virtual product launch that took place on October 13, 2020, together with our OEM partner, STOE & CIE GmbH, we have presented the new system, its key specifications and benefits, as well as the first results obtained.

An HPC detector for any wavelength

“Better data from both strong and weak signals, sharp reflection profiles and an excellent spot separation, and high quantum efficiency for short and dual-wavelength setups,” is how Dr. Marcus Müller, Product Manager XRD at DECTRIS, summarizes the key benefits of the EIGER2 R CdTe for its users. Its small pixels, superior count rate, simultaneous read/write, and the two energy-discriminating thresholds allow for superior dynamic range, while the cadmium-telluride sensor enables up to four times faster data collection.

The detector has been tested in STOE’s dual-beam setup with a silver (Ag) and a copper (Cu) source and it performed well under both hard and soft radiation. “The new EIGER2 R CdTe features the best of HPC technology and cadmium-telluride sensor: we gain an improved resolution thanks to the detector’s chip and very high quantum efficiency through the new sensor material,” explained Dr. Jens Meyer, an application scientist at STOE.

EIGER2 R CdTe completes the DECTRIS cadmium-telluride-sensor-based product family. With its frame rate capability and calibration optimized to match the requirements and characteristics of all common laboratory sources, it is a twin brother of its synchrotron counterpart, EIGER2 X CdTe. Coming in three different geometries and sizes and with optional vacuum compatibility, EIGER2 R CdTe fulfills the requirements of almost any experimental setup you can think of.
