PHYWE Multichannel Analyser (MCA)

Продукт No: 13727-99
Function and Applications

The multichannel analyser is for analysing voltage pulses which are proportional to energy and for determining pulse rates and intensities in conjunction with an X-ray detector, alpha detector or gamma detector. The analogue pulses from the detector are shaped by the analyser, digitised and summed per channel according to pulse height. This results in a frequency distribution of detected pulses dependent on the energy of the radiation.

Equipment and Technical Data

The multi channel analyser has an offset function for enhancing the energy resolution.
It possesses the following features:

  • Analogue output for observing heights of the pulse spectrum on an oscilloscope,
