PHYWE Multichannel Analyser (MCA)
Article No: 13727-99
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.
