Real-Time Digital Pulse Processor (DPP) and Digital MCA in One Package. The nanoMCA is a full-featured multichannel analyzer. The ultra low power nanoMCA is based on real-time digital pulse processing, allowing for high counting rates without sacrificing spectroscopy performance. 

Check out how the nanoMCA compares to Amptek and Ortec devices.

The nanoMCA is a state-of-the-art small, low power, high performance digital MCA, featuring:

  • Full featured 80MHz Digital Pulse-Processing (DPP) Multichannel Analyzer (MCA)
  • Two analog inputs supporting reset and resistive feedback preamplifiers and user-shaped pulses, including pulses from analog spectroscopy amplifiers
  • Pulse-Height Analyzer for pulses from Analog Shapers (PHA mode)
  • Free labZY-MCA software for device configuration, spectra acquisition, and spectrum analysis
  • Built-in Trace Viewer, the most advanced detector signal exploration tool
  • Automatic functions: thresholds, pole-zero, input polarity, inhibit polarity
  • Built-in coincidence logic with delays and coincidence window generator
  • Convenient and flexible connectivity
    • I/O: Single mini USB connector also power source
    • Power: USB, mini wall adapter, or optional battery
    • Device interface: Wired or wireless (USB, Ethernet, WiFi, Bluetooth)
  • Exceptional temperature stability
  • Small size (92 mm x 38 mm x 25 mm) and low power (850 mW typ)

  • Getting Started with nanoMCA [pdf]
  • Download the nanoMCA Example Spectra here [zip]
    • The example spectra were taken using regular detectors without shielding or special preparation. Four sets of detectors were used, specifically: LaBr, RC-HPGE, SP, and TRP-HPGE detectors. Some notes about the detectors:
      • The labZY detectors, including the HPGE detectors, are more than 20 years old
      • The TRP-HPGE detector was specified as new with a resolution of 1.9keV@Co-60. The measured resolution using the nanoMCA is consistently 1.7keV
      • The RC-HPGE detector has lost some vacuum but still produces interesting spectra at short shaping times
      • The LaBr scintillation detector is the only detector which does not belong to labZY
