Amptek has developed a 70 mm² FAST SDD® Detector in a TO-8 package. This is the same package that is used with all Amptek detectors. This makes the 70 mm² a drop in replacement (same package, same pin-out, same voltages). Triple the count rate vs. the 25 mm² SDD with the same performance.

  • 70 mm² active area collimated to 50 mm²
  • 123 eV FWHM resolution at 5.9 keV
  • Count rates > 2,000,000 CPS
  • High peak-to-background ratio – 26,000/1
  • Preamplifier Output Rise Time <60 ns
  • Windows: Be (0.5 mil) 12.5 µm, or C2 (Si3N4)
  • Radiation hard
  • Detector thickness 500 µm
  • TO-8 Package
  • Cooling ΔT>85 K
  • Multilayer Collimator

Applications

  • Ultra-fast benchtop and handheld XRF analyzers
  • Scanning/mapping of samples in an SEM as part of an EDS system
  • On-line process control
  • X-Ray Sorting Machines
  • OEM
