Abstract-The simulation of radioactive decays is a common task in Monte-Carlo systems such as Geant4. Usually, a system either uses an approach focusing on the simulations of every individual decay or an approach which simulates a large number of decays with a focus on correct overall statistics. The radioactive decay package presented in this work permits, for the first time, the use of both methods within the same simulation framework -Geant4. The accuracy of the statistical approach in our new package, RDM-extended, and that of the existing Geant4 per-decay implementation (original RDM), which has also been refactored, are verified against the ENSDF database. The new verified package is beneficial for a wide range of experimental scenarios, as it enables researchers to choose the most appropriate approach for their Geant4-based application.

“…Simulations were carried out using the two different implantation profiles of the source distribution conditions in the Si layers as discussed above. The -decay energy distribution can be user defined or the known -decay energy distribution of any nuclei can be called from the Radioactive Decay data base of Geant4 [35]. The RadioactiveDecay data base follows the decay information from Evaluated Nuclear Structure Data File (ENSDF) (2013 version) [36].…”

A Geant4 simulation has been carried out in order to determine the -detection efficiency of a rare isotope beam implantation setup, for decay spectroscopy experiments, comprising a number of Double Sided Silicon Strip Detectors (DSSSDs) and two plastic scintillation detectors placed upstream and downstream. The absolute efficiency for the emitted -particle detection from radioactive fragments implanted in the DSSSDs using fasttiming plastic-scintillator detector, is calculated. The detection efficiency of the setup has been studied with two different distances between the Si layers and plastics. The requirement for the thickness of the Si detector layers and its implication on the -detection efficiency has been investigated for 1 mm and 300 μm thickness of Si layers. The combined efficiency of DSSSD and plastic detectors were also simulated for two different thicknesses of the DSSSD.Plastic scintillator detectors are widely used in nuclear and high 2 energy physics experiments due to their excellent time response, low 3 stopping power, relatively low cost and versatility. These detectors 4 are also commonly used in decay measurements [1-4] alongside 5 Double Sided Silicon Strip Detectors (DSSSDs) [5]. The fast time re-6 sponse of plastic scintillator detectors and the good position resolution 7 of DSSSD makes them complementary in measurements where high 8 quality of both position and time response are demanded. A closely 9 packed setup comprising stacks of DSSSDs and plastic detectors are 10 chosen for the DEcay SPECtroscopy [6,7] setup, as a part of NUS-11 TAR [8,9] experiments at GSI [10] and FAIR [11,12]. A similar setup 12 was installed previously for decay spectroscopy measurements with 13 radioactive ion beams at RIKEN [13-15]. The DESPEC experiments will 14 use the active implantation detector array, AIDA [16,17] for isomer 15 decay spectroscopy measurements as well as for the spectroscopy of the 16 daughter nucleus post decay of the implanted fragments. The DESPEC 17 experiments aim at studying extremely rare isotopes produced via 18 fragmentation of heavy nuclei namely 238 U [18-20]. The background 19 radioactivity is generally orders of magnitude higher than the rate 20 of decay events from nuclei of interest. As a result, event by event

“…For both detectors, the sources 22 Na, 54 Mn, 57 Co, 60 Co, 65 Zn, 109 Cd and 133 Ba were simulated for comparison with experimental data, placed 25 cm away from the cryostat window of the detector. In the case of the IF-BEGe, the sources were simulated as ions with the GEANT4 General Particle Source and their decays with the Radioactive Decay Module [22]. For the ICN-HPGe, the simulations were performed emitting mono-energetic γ-rays corresponding to the emission energy of each isotope, see table 1.…”

A: This article reports the characterization of two High Purity Germanium detectors performed by extracting and comparing their efficiencies using experimental data and Monte Carlo simulations. The efficiencies were calculated for pointlike γ-ray sources as well as for extended calibration sources. Characteristics of the detectors such as energy linearity, energy resolution and full energy peak efficiencies are reported from measurements performed on surface laboratories. The detectors will be deployed in a γ-ray assay facility that will be located in the first underground laboratory in Mexico, Laboratorio Subterráneo de Mineral del Chico (LABChico), in the Comarca Minera UNESCO Global Geopark [1].
