A systematic literature reviews of multichannel analyzer based on FPGA for gamma spectroscopy

Abstract

Environmental radiation monitoring based gamma spectroscopy require a multichannel analyzer (MCA) which functions to record and analyze nuclear radiation spectrum data. There are currently many studies related to MCA based on field programmable gate array (FPGA). But, the scope of these published research is complex and fragmented. This systematic literature review (SLR) main objective to analyze research trends and emerging themes research of MCA based on FPGA for gamma spectroscopy that was developed during last 10 years. This review was conducted by selecting papers from leading journals in scientific databases namely ScienceDirect, IEEE Xplore and Scopus. For papers selection process, specific keyword strings used for each database and paper selecting using inclusion and exclusion criterion. Selection of papers resulted in 38 selected papers. During 10 last 10 years, This reseach become hot of topic research especially in Asia. This SLR proves that performance of MCA based FPGA is reliable and compatible with various of detector types. This MCA has been used for spectroscopy applications such as monitoring radiation, diagnostic medicine, industrial imaging and security screening. The implications of this study can used as reference for future research of development MCA based FPGA for enviromental radiation monitoring based gamma spectroscopy.

Development of low-cost digital gamma spectrometer using ARM Cortex-M Type Microcontroller Unit

“…The output pulses from the detector are then delivered to a digital pulse processing (DPP) unit which computes the energy spectrum of the striking gamma photons. The computed spectrum is then sent to a display or a computer to plot it [2][3][4]. One of the main components of the DPP unit is the analog-to-digital (ADC) converter.…”

Experimental investigation of the ADC sampling rate effect on the digital gamma spectrometry

“…It is used as a tool to measure and identify radioisotopes. Recently, digital gamma spectrometers are widely used due to their reliability, stability, flexibility, and compact size [1,2]. Figure 1 presents the block diagram of the digital gamma spectrometer.…”

“…The ADC's sampling rates of these prototypes are not the same. The sampling rate of the ADC plays the main role in determining the performance and the cost of the gamma spectrometers [1,2]. As the sampling rate of the ADC is reduced, the cost of the ADC reduces.…”

“…The implementation of very low-cost and efficient gamma spectrometers is a hot research topic nowadays [1,[7][8][9][10][11][12]. This target may lead later the gamma spectrometers to be easily available in many research and academic laboratories.…”

Developing of a Virtual MCA to Acquire a Radiation Spectrum

“…A FPGA-based digital gamma spectrometer was developed by Liu et al [14]. For gamma spectroscopy, a systematic literature review of MCA based on FPGA was given by Susanto et al [15]. An online digital signal processing system based on an FPGA was developed by Kim et al The system was tested for gamma rays from 137 Cs [16].…”
