WebABSTRACT: A multichannel pulse-height analyzer system (MCA) consists of an ADC with 8192 channel performance, a histogramming memory, and a visual display of the histogram, implemented on a Personal Computer (PC). The purpose of the analog-to-digital converter (ADC) is to measure the maximum amplitude of an analog pulse, and WebWhen mono-energetic radiation is incident on a detector and the energy (or pulse height) spectrum is measured, the peak produced by full-energy deposition is Gaussian as shown in Fig. 2.3 if the number of counts is sufficient enough. The energy resolution of a peak can be expressed as the width of the peak. my northwest state community college https://wearevini.com
