nanoPSD

Real-Time Digital Pulse-Shape Discriminator (PSD) and Spectrometer with Simultaneous Amplitude and Pulse-Shape Discrimination. The nanoPSD is a digital spectrometer with embedded pulse-shape analyzer and pulse-shape discriminator. See a list of key features below and the data sheet for a full description of the nanoPSD’s features and specifications. 

The nanoPSD is a compact digital spectrometer, with an embedded pulse-shape analyzer and discriminator, featuring:

  • Real-time digital pulse-shape discrimination based on labZY’s proprietary ballistic deficit measurement
  • Simultaneous pulse-height  and pulse-shape discrimination
  • A built-in PMT preamplifier with selectable sensitivity (8 settings)
  • Time-invariant signal processing with zero dead time apart from memory acquisition
  • High counting rates  (e.g., > 3 mln cps incoming for LaBr and fast organic detectors)
  • Simultaneous acquisition of one Time-Invariant Pulse-shape Signatures (TIPS) spectrum and three Pulse-Height spectra
  • Enhanced pile-up rejection and automatic threshold settings
  • Built-in Trace Viewer, the most advanced detector signal exploration tool
  • USB powered with flexible wired or wireless connectivity at low power (900 mW)
  • Free labZY-PSD software for device configuration, PSD settings, spectra acquisition, and basic analysis
