A method for digital processing of pile-up events in organic scintillators

Stimulus generation technique for code simulation of FPGA based gamma spectroscopy system

“…Single/Pile-Up Mode enable user to generate pile-up at various degrees and analyze the effects. This is useful especially in testing and verifying pile-up rejection and correction algorithm in digital processors [20][21] [22]. Single/Pile-Up mode consists of 2 pulse sources, S 1 and S 2 .…”

Application of Virtual Instrumentation in Nuclear Physics Experiments

“…In the case of nuclear detectors, when high activity sources and detectors with a long pulse decay time are used, two or more events can be recorded as a single event. Various methods are used for the detection and either the correction or rejection of these pulses (Cosulich et al, 1992;Belli et al, 2008). The pile-up affects the counting rate, energy and time resolution of the spectroscopy system.…”

“…The paper presents two simulated experiments that can be easily as well as remotely accessible (γ-energy determination and Mössbauer spectroscopy). Digital acquisition system (Belli et al, 2008) for digital pulse processing is applied to acquire data from n-γ detectors. It is based on FPGA.…”

A study on fast digital discrimination of neutron and gamma-ray for improvement neutron emission profile measurement

“…[2][3][4] Recently, a digital signal processing (DSP) system equipped with a fast flash analogto-digital converter (Flash ADC) has been used for such measurements. [3][4][5][6][7][8][9] The output waveform from an anode of a photomultiplier tube (PMT) is recorded using a Flash ADC and is analyzed off-line. The DSP system is applicable for measurement under high-counting-rate conditions in which analog processing is impossible to use.…”

“…1,8,10,11 A charge comparison method was applied to pulse signals from the scintillation detector, where neutrons and γ -rays are discriminated through comparison of pulse shape attenuation. [3][4][5][6][7][8]11 In the conventional pulse comparison method, each pulse signal is integrated in two time intervals. Using the results, a twodimensional (2D) map was drawn.…”
