Application of alpha particle transport to the modelization of efficiency curves in proportional counters

Application of the new Monte Carlo code AlfaMC to the calibration of alpha-particle sources

“…An alternative method to calculate the desired corrections to the counting rate in 2 detection systems is the use of Monte Carlo simulation to model the behavior of the particles in the source and backing. Some works have been published using this procedure [11][12][13][14], using the well-known code SRIM [15].…”

A comparison between the codes SRIM and AlfaMC in the Monte Carlo simulation of alpha-particle backscattering

“…The main drawback of some general-purpose Monte Carlo codes applied to the particle transport, such as MCNPX [8] or GEANT4 [9] is their high computational charge, resulting in very slow calculations. Several simulation studies to deal with alpha-particle backscattering have been published [7,[10][11][12], most of them by using the well-known code Stopping and Range of Ions in Matter (SRIM) [13], developed for ion tracking in matter. SRIM provides faster results and easier implementations than the general purpose codes but it can only be applied to simple slab geometries.…”

“…Perhaps, the main drawback of this code is that can be only applied to simple slab geometries. It has already been used by us for many applications in the field of alpha-particle spectrometry [15,16]. In this work, the last known version of SRIM [17] was used.…”
