PHYWE Multichannel Analyser (MCA)

Article 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.

Benefits

  • Offset function for enhancing  energy resolution

  • For spectroscopy and x-ray fluorescence analysis
