eMorpho Product Description

eMorpho - Embedded Digital MCA

The eMorpho MCAs are high-performance multi-channel analyzers designed from the ground up for use with scintillator detectors. They include a USB-1.1 interface and can be powered directly through the USB port.

Digital MCA works with any scintillator:

The eMorpho MCA line is based on the principle of waveform digitizing and digital signal processing. There are no built-in limitations, such as fixed time constants. The eMorpho MCA can digitally integrate short spikes just as well as slow decay signals. Perfomance is not impacted by non-exponential signals or multiple time constants in the scintillator light. With an eMorpho MCA you will get the most accurate spectra for virtually all commercially available scintillators.

High-speed MCA

Unencumbered by analog shaping, the eMorpho processes the scintillator pulses as fast as their pulse shape allows. For all but the very fastest scintillators the achievable histogramming rate is limited only by the characteristics of the scintillator and not the MCA. Hence, the eMorpho MCA will provide the highest histogramming rate possible.

Accurate rate measurement

The eMorpho provides highly accurate count rate measurements, especially at very high count rates.

Extended capabilities

Many applications require added functionality beyond histogramming. And the eMorpho supports that with a range of extended capabilities. As an example, the graph to the right shows the pulse shape of a CsI(Na) scintillator crystal. The eMorpho extended capabilities include:

  • Online pattern recognition to support phoswich detectors
  • Waveform capture for diagnostics and research
  • List mode data acquisition storing energies and time stamps for monitoring applications
  • Unit-to-unit daisy chaining allows to distribute clocks, triggers and data

Accurate calibration

The eMorpho is an accurately calibrated device, that measures anode currents (μA) and pulse charges (nC) with an absolute precision of ±1.0%.

Low cost, small size, low power

The eMorpho packs all its capabilities into a very small foot print—a 2-inch diameter PCB that can be embedded with 2-inch PMTs, with a power consumption as low as 0.33 W, and at a very competitive price.
