DSPEC 50 and DSPEC 502 Advanced, Fourth-Generation ORTEC DSP-Based Gamma Ray Spectrometers for Germanium Detectors

Hardware Features
  • Single MCA (DSPEC 50) and dual MCA (DSPEC 502) versions.
  • Highly stable against variations in count rate and temperature.
  • PHA and List Mode acquisitions.
  • Automated set-up: Automatic Pole Zero Adjust, Baseline Restorer, and Optimize.
  • High throughput capabilities for high count rate applications.
  • Digital spectrum stabilizer.
  • USB 2.0 and Ethernet capability (TCP/IP protocol).
  • Large front panel display for at-a-glance system status information.
  • Support for all HPGe detector types, old and new.
Advanced DSP Algorithms Ensure Enhanced Spectroscopic Performance
  • Correct treatment of highly variable count rates and short half lives: ZDT “loss free” dead-time correction withuncertainty calculation.
  • Low Frequency Rejection (LFR) mode improves resolution by rejection of low frequency noise, e.g., electrical linenoise or vibration-induced microphonics.
  • Resolution Enhancer improves FWHM of HPGe detectors with degradation due to charge trapping, e.g., fromradiation damage.
  • Enhanced Throughput Mode for the ultimate in high throughput counting, up to 30% boost in system throughput.
