EIGER R pixel detector Overview:

The EIGER2 detector is the latest masterpieces of DECTRIS AG. It features a newly designed sophisticated read-out system with dual energy discrimination that effectively suppresses background and improves signal-to-noise. Two analog circuits allow for simultaneous read and write operation with NO DEADTIME!  As its precessor, the EIGER detector, it has a frame rates of 10Hz (EIGER R 1M) or 5Hz (EIGER R 4M), respectively, and a small pixelsize of only 75 microns (PILATUS3: 172 microns) and hence a larger amount of pixels as compared to a PILATUS3 detector of the same physical dimension. 

marXperts now also offers full support for the EIGER2 and EIGER series of detectors with our mardtb goniostat. In fact, the EIGER2 and EIGER detectors are the perfect fit for the mardtb and data collection is fully integrated into our well-known data collection software.

The key advantages of using a EIGER(2) detector with the mardtb are as follows:

  • extremely short read-out time of 10 microseconds allows for fine φ-slicing
  • very small pixel size of only 75 microns
  • 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 extremely short read-out time paired with an excellent sensitivity makes the EIGER(2) R series of detectors highly suitable for in-house data collection or crystal screening on home lab X-ray sources like Excillum Metaljet, 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(2) 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.

mar4MUpgrade of  mar345dtb  to  EIGER R 4M (mar4M) or EIGER R 1M:

Existing mar345dtb detector sytems can easily be upgraded with an EIGER detector, i.e.  the mardtb can be used together with the EIGER(2) R 4M or EIGER(2) R 1M detector. Due to its larger detector surface that eliminates requirements for collecting multiple data sets at 2-theta offsets, the EIGER(2) R 4M detector clearly is your first choice.  When  using the small EIGER R 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. For this special combination the range of movement of the distance translation stage of the mardtb goniostat is 22 to 150 mm for the EIGER R 1M detector and 120 to 425 mm for the mar345 detector.


mardtb desktop beamline with Eiger R 4M detector
mar345dtbThe EIGER(2) R 4M or 1M 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).
marmuX2G Data Collection System marmot marmux2gmarYX2G: An EIGER(2) R 4M or 1M detector with a mardtb goniostat in combination with a marµS microfocus generator. 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 for the ultimate performance in the home lab, a combination of a MetalJet X-ray source with a EIGER(2) 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!
