PLEIADES XRA-700 Detector Array

PLEIADES XRA-700 Detector Array

The XRA-700 is a multichannel X-ray spectroscopy system, with seven high-performance X-ray detectors with low noise preamplifiers, plus the control unit with power supplies and cooling. Utilizing Amptek’s rich history in XRF technology, and broadest portfolio of available detectors on the market, the XRA-700 can be configured with seven of the same detectors, or with a variety of detectors to meet the needs of the application.

As standard, the system is configured with seven 70 mm2 FAST SDD® detectors, but other options include:

  • 70 mm2 FAST SDD with a C2 window (40 nm of Si3N4) for detecting X-rays down to the Be Kα line.
  • 1 mm thick 70 mm2 FAST SDD for up to 2x better intrinsic efficiency at high energies.
  • CdTe detectors with good efficiency up to 150 keV.
  • Benefits +


    • Can be configured with seven identical detectors, or for any combination of the detectors, to better optimize the sensors for a particular measurement.
    • Compatible with third-party multi-channel digital pulse processors.
    • In the event a window breaks, only 1 detector fails, the remaining detectors continue functioning as normal so you can keep running your experiment.
    • Design allows for faster and more economical replacement of an individual detector.
