MULTICHANNEL PULSE HEIGHT ANALYSER USING FPGA FOR DATA ACQUISITION

Abstract

This document gives the description of a multichannel pulse height analyser which is implemented using FPGA technology for high speed data acquisition and analysis. Multichannel analysers (MCA) are used globally in various laboratories in the application of nuclear spectroscopy. The most common use of a MCA is to plot the energy spectrum or to find the decay rate of the radio material under test. In the following context we have described the designing of an open source multichannel pulse height analyzer which uses a high speed ADC for data acquisition and displays the output on a graphical user interface designed using labVIEW in a computer.
