EIGER 1M EIGER 4M mardtbEIGER Hybrid Photon Counting Detectors

EIGER R pixel detector Overview:

The EIGER is the latest masterpiece of DECTRIS AG. As the famous PILATUS3, it is a hybrid photon counting detector. It features a virtually continuous read-out system with up to 3000 Hz frame rate and virtually no dead-time (4 microseconds !). For home lab use, the frame rate of the R series is restricted to 10Hz (EIGER 1M) or 5Hz (EIGER 4M). The main benefit as compared to the PILATUS3 detectors is the small pixelsize of only 75 microns (PILATUS3: 172 microns) and hence the larger amount of pixels as compared to a PILATUS3 detector of the same physical dimension. 

marXperts now also offers full support for the EIGER series of detectors with our mardtb goniostat. In fact, the EIGER detectors of any size fit nicely on the mardtb and data collection is fully integrated into our well-known data collection software.

The key advantages of using a EIGER detector with the mardtb are as follows:

  • extremely short read-out time of 3 ms allows for fine φ-slicing
  • shutterless data collection
  • extremely high sensitivity
  • extremely low noise
  • high dynamic range (32 bits)
  • no point-spread due to direct conversion leading to small spots with better I/σ  
  • fast screening experiments

The short read-out time paired with an excellent sensitivity makes the EIGER series of detectors highly suitable for in-house data collection or crystal screening on conventional X-ray sources like the marYX2G X-ray data collection system or rotating anode generators. Thanks to the very short read-out time the usual way of collecting data with the EIGER detectors is to leave the shutter open until the end of data collection ("shutterless operation"). This reduces an instrument error factor and may be beneficial to the data quality.

mar345dtb mar200k mar1MUpgrade of  mar345dtb  to  EIGER 1M or 4M:

Existing mar345dtb detector sytems can easily be upgraded with an EIGER detector, i.e.  the mardtb can be used together with a EIGER 1M or 4M detector.  When  using the small EIGER 1M detector, it is possible to mount the detector in front of the mar345 mar345smar345 detector. One can then easily take away the small EIGER detector and use the large mar345 image plate detector if there is a need for a large detector surface. The only drawback for this special combination is that the range of movement of the distance translation stage of the mardtb goniostat is somewhat restricted: 22 to 150 mm for the EIGER 1M detector and 120 to 425 mm for the mar345 detector.

mar345dtbThe EIGER R 1M or 4M detector is mounted on a mardtb goniostat. The mardtb  “desktop beamline” features a fully automatic beam alignment system and more than 10 motors including an “inverted PHI” assembly and a 2-theta stage. The system can be operated with any X-ray source (sealed tubes to synchrotrons).
Note: The photo on the right hand side shows a PILATUS3 200K system, but the EIGER 1M will actually look very similar...

This system is the perfect choice, when cost-of-ownership and maintenance issues come into play. Despite of the low price, the system is highly suitable for fast screening experiments, but also for complete data collections of small crystals and other kinds of diffraction experiments.
Excillum MetalJet X-ray source MetalJet high end system: If you are aiming at the ultimate performance in the home lab, a combination of a MetalJet X-ray source with a EIGER R 4M detector and a mardtb goniostat is the very best you can obtain today. Excillum's patented MetalJet technology beats any other conventional X-ray source in terms of brilliance and is a true alternative to a synchrotron. Please contact us for further details!
