Hard X-ray imaging detector

The Technology department at STFC have developed the HEXITEC detector measures the energy and position of every incident photon in the 4-200keV range. Each one of the 80x80 pixels provides a full energy spectrum with an average energy resolution of 800eV FWHM at 60keV.




The GigE 8080 is a self-contained, CE marked module that only requires a mains power supply and connection to a PC or Laptop. It can be supplied with a user friendly GUI to operate the detector and provide calibrated spectra per pixel or industry standard Gig-E-Vision APIs for users to integration into their own systems.


The unique high energy dispersive X-ray imaging capability of the HEXITEC detector has been demonstrated in a number of applications including:

    •  Energy dispersive diffraction imaging

    •  X-ray fluorescence imaging

    •  K-edge enhanced imaging

    •  Multiple radio-isotope SPECT


HEXITEC has the potential to use these techniques in scientific and industrial inspection, security scans and medical imaging.
