Orion Multi-Channel Analyzer

The Orion MCA is the latest and most advanced Multi-Channel Analyzer of its kind. A spectrometer with 64K channels and 100% digital signal processing. Additionally, the Orion features a 100 MHz 16 bit sampling ADC, an internal Linux computer, and internal high voltage bias supply. It includes impressive pulse processing features such as pulse height analysis, list and peak shape data acquisition, detector digital signal processing, and filtering with a variety of shaping times.

The Orion MCA offers both USB and Ethernet communication and a time stamp for each event down to 12.5 nanosecond resolution. The Orion's front panel display includes a 3.5” TFT touch screen with several languages, offering autoranging of peak counts and a calibrated horizontal axis displaying energy. LEDs confirm serial or Ethernet communication with a PC. Other LEDs confirm HV and warn of a system or detector problem. There is no other instrument on the market that can match these features.

Orion is controlled by InterWinner, the most user-friendly yet advanced spectroscopy package on the industry.

The Orion is available in benchtop or in a NIM-style package without the integral HV supply or touch screen display.


Touch Screen Interface Features Include:
  • Setting and enabling of the high voltage Oscilloscope with trigger
  • Gain and input polarity setting
  • Automatic setup, including automatic energy calibration
  • Spectrum display, including zoom and ROI marking Peak search Analysis, including activity calculation
  • Automatic spectrum storage Recall stored spectra Global gamma analysis including calibration of efficiency and background
  • Visualize the system health status Export spectra to USB stick
