Pair Distribution Function (PDF) Analysis / Total Scattering

One of the major requirements for obtaining high-quality data through  Pair Distribution Function Analysis is a detector that covers a wide Q-range via a combination of wide angular coverage and utilization of high-energy X-rays. 

One of the first photon-counting detectors that were employed for this task was a MYTHEN model, due to its ability to build multi-modular systems (wide angular coverage), its 50-μm strip (resolution), its high dynamic range, and its efficiency at moderately high energies. However, with the rise of beamlines that use high X-ray energies, the focus has shifted to large-area pixel detectors with a CdTe sensor, which offers high efficiency for hard X-rays. Featuring no image lag and no afterglow, these detectors provide an opportunity to take static and dynamic measurements up to 100 keV. 
  
Laboratory diffractometers, meanwhile, operate with Mo or Ag X-ray sources and combine them with area EIGER2 detectors or linear MYTHEN2 systems. Angular coverage is achieved through wide sensors, as well as a frame rate that supports fast scanning modes.

• We offer strip detectors with a thick Si sensor for the mid-range X-ray regime and CdTe detectors for hard X-rays.
• Our detectors feature small pixels and strips with a high count rate for optimal resolution and data statistics.
• Achieve wide angular coverage using our large-area pixel detectors and multi-modular microstrip detectors.
