The UltraDry EDS Detector Features:

  • Extraordinary operating space to enable superior performance with advanced field-effect transistor (FET) integration and a proprietary preamplifier stage 
  • A smaller, integrated FET to virtually eliminate electronic noise
  • Minimized dead time and maximized resolution to effectively handle pulse pile-up and sum peaks
  • Eliminated external or liquid nitrogen cooling with while maintaining extremely high data collection rate 
  • Consistent data collection rates across the widest range of distances — absolutely critical to dual EDS and EBSD acquisition — with unique slotted collimator design
  • One of the greatest solid angle of collection available for detectors on the market today with crystal active area range (10mm2, 30mm2, 60mm2, 100mm2) and small packaging envelope
  • FWHM measured (ISO 15632) at 5.89keV (Mn-Kα) with 10,000 counts per second stored in the spectra, measured on the electron microscope
  • WD range is measured by varying the vertical distance between the pole piece and the surface of the sample and measuring the input count. STD distance of 50mm. TOA of 35°. The range is defined as within 25% of the peak count rate at the optimized working distance.
  • Vertically slotted collimator to enable maximum WD range. Absolute requirement for dual EDS/EBSD acquisition mode.
  • Light element sensitivity down to beryllium
  • No auxiliary cooling connections, water or fans. No liquid nitrogen.
  • Operating environment to 35 °C
  • ±5 eV resolution change (±3eV typical between 1% and 60%dead time) from minimum to maximum count rate at a givenanalyzer time constant
  • ±5eV peak shift (±3eV typical between 1% and 60% deadtime) from minimum to maximum count rate at a given analyzertime constant
  • Input count rates >1,000,000 counts per second
  • Motorized slide optionally available
