EXAFS Detectors

Quantum Detectors builds some of the world’s leading detectors specifically designed for dispersive beamlines by beamline scientists and detector engineers sited together at the UKs synchrotron facilities.

This development process has lead to detectors boasting capabilities including 100,000 frame per second count rates.

The detectors supplied by Quantum Detectors for EXAFS come in three types to suit a large range of requirements. The highest performing of these is the XH, with a sensitivity upto 30KeV using germanium microstrip technology. Both the XH and XSTRIP achieve rates of 100KHz, the XSTRIP uses silicon microstrip technology and is almost 100% efficient between 5 and 15KeV. The ULTRA system captures at a rate of 20KHz, but comes in an attractive form factor (150x150x200mm) and is easily connected via Gigabit Ethernet.

These detectors enable the exploration of a wide range of dynamic experiments and time regimes unavailable using other systems. This timing capability combined with the sensitivity, ease of use and high level of support are a strong option for any dispersive EXAFS beamline looking to upgrade. A few of the key features are listed over the page.

  • Benefits

  • Low noise performance
  • Sensitivities from 5-30KeV

    • Detector ULTRA XSTRIP XH
    Description The ULTRA DAQ and ULTRA Detector combination provide a 1D position sensitive detector with sensitivity in the range 5-15KeV using a custom Silicon sensor. With an impressive 512 pixels and a readout of >20KHz ULTRA is an impressive start to our lineup. With frame rates upto 100KHz and 1024 pixels, the XSTRIP detector is a world leading system for uncovering science in new time regimes for soft x-rays at 5-15KeV. Using pioneering Germanium bonding technology, the XH from Quantum Detectors is the perfect system for mid - hard x-ray dispersive EXAFS. With high sensitivity upto 30KeV and rates upto 100KHz this detector is at the cutting edge of EXAFS instrumentation.
