“…The combination of FLUKA with FLAIR hold the advantage of usability and simplicity over other Monte-Carlo software which are based on command-line interface. While FLUKA is extensively used in high-energy physics, medical physics and radioprotection [16][17][18][19], there are very few works that applied FLUKA in studies involving gamma-ray spectrometry.…”

The detection efficiency of a broad-energy germanium detector was determined empirically and compared to predictions by the Monte-Carlo software GEANT4 and FLUKA . The considered source geometries were point-like, filter paper and a water beaker. Calculations were performed in the photon energy range of 30–1836 keV . Simulated detection efficiencies obtained from both Monte-Carlo software were found to be in a good agreement (typically <5%) with experimental results for the considered source geometries. A comparison between the detection efficiencies obtained with GEANT4 and FLUKA codes exhibited a good agreement with a robust average of approximately 1%.

“…All the above is complemented by a long-standing initiative to generate new experimental data for benchmarks of radiation transport simulation codes with a focus on the relevance to real-world applications. Examples are neutron spectra at the CERN-EU High-Energy Fields (CERF) facility [45][46][47], neutron spectra and activation at the CERN Shielding Benchmark Facility (CSBF) [48,49], activation at the CERN High-energy AcceleRator (CHARM) test facility [50] and activation due to stray radiation from the annihilation of lowenergy antiprotons in steel [51].…”

FLUKA is a general purpose Monte Carlo code able to describe the transport and interaction of any particle and nucleus type in complex geometries over an energy range extending from thermal neutrons to ultrarelativistic hadron collisions. It has many different applications in accelerator design, detector studies, dosimetry, radiation protection, medical physics, and space research. In 2019, CERN and INFN, as FLUKA copyright holders, together decided to end their formal collaboration framework, allowing them henceforth to pursue different pathways aimed at meeting the evolving requirements of the FLUKA user community, and at ensuring the long term sustainability of the code. To this end, CERN set up the FLUKA.CERN Collaboration1. This paper illustrates the physics processes that have been newly released or are currently implemented in the code distributed by the FLUKA.CERN Collaboration2 under new licensing conditions that are meant to further facilitate access to the code, as well as intercomparisons. The description of coherent effects experienced by high energy hadron beams in crystal devices, relevant to promising beam manipulation techniques, and the charged particle tracking in vacuum regions subject to an electric field, overcoming a former lack, have already been made available to the users. Other features, namely the different kinds of low energy deuteron interactions as well as the synchrotron radiation emission in the course of charged particle transport in vacuum regions subject to magnetic fields, are currently undergoing systematic testing and benchmarking prior to release. FLUKA is widely used to evaluate radiobiological effects, with the powerful support of the Flair graphical interface, whose new generation (Available at http://flair.cern) offers now additional capabilities, e.g., advanced 3D visualization with photorealistic rendering and support for industry-standard volume visualization of medical phantoms. FLUKA has also been playing an extensive role in the characterization of radiation environments in which electronics operate. In parallel, it has been used to evaluate the response of electronics to a variety of conditions not included in radiation testing guidelines and standards for space and accelerators, and not accessible through conventional ground level testing. Instructive results have been obtained from Single Event Effects (SEE) simulations and benchmarks, when possible, for various radiation types and energies. The code has reached a high level of maturity, from which the FLUKA.CERN Collaboration is planning a substantial evolution of its present architecture. Moving towards a modern programming language allows to overcome fundamental constraints that limited development options. Our long term goal, in addition to improving and extending its physics performances with even more rigorous scientific oversight, is to modernize its structure to integrate independent contributions more easily and to formalize quality assurance through state-of-the-art software deployment techniques. This includes a continuous integration pipeline to automatically validate the codebase as well as automatic processing and analysis of a tailored physics-case test suite. With regard to the aforementioned objectives, several paths are currently envisaged, like finding synergies with Geant4, both at the core structure and interface level, this way offering the user the possibility to run with the same input different Monte Carlo codes and crosscheck the results.

“…In the literature, several articles were reported based on the study of the shielding properties of indiumcontaining oxide and non-oxide glasses [14][15][16][17][18][19][20][21][22][23][24] but no report of indium-containing non-oxide chalcogenide glasses was found. Dai et al observed the high collection carrier capacity of indium tin oxide (ITO) film by irradiating it with 1 MeV energy and suggested that ITO film can be applied in the manufacturing of space solar cells [14].…”

“…Katagiri et al synthesized a thin film of perhydropolysilazane and hydrophobized indium tin oxide nanoparticles, which have an extreme IR-shielding ability to block IR radiation of more than 1400 nm wavelength [17]. Ahdida et al experimented with exposing aluminum, bismuth, and indium samples to annihilate stray radiation and compared these results with FLUKA Monte Carlo simulations, finding that the measured values are better than a factor of two [18]. The measurement of the distribution of fast neutrons in large areas using indium foils was demonstrated by Kobayashi et al [19].…”

This paper reports the study of the high-energy radiation shielding characteristics of the STS glassy system. Further, the work investigates the effect of indium concentration on the high energy radiation shielding characteristics of the STS glassy system. For this purpose, a glassy Se78-xTe20Sn2Inx (x = 0, 2, 4, and 6) system was synthesized using a renowned melt quench technique whose density was measured through the Archimedes method. We have utilized an online platform, i.e., Phy-X/PSD software, to measure the different radiation shielding parameters of the SeTeSnIn glassy system. Several shielding parameters such as linear and mass attenuation coefficient, half value layer (HVL), mean free path (MFP), effective atomic number (Zeff), effective electron density (Neff), effective conductivity (Ceff), equivalent atomic number (Zeq), energy absorption build-up factor (EABF), exposure build-up factor EBF), and fast neutron removal cross-section (FNRCS) have been measured in the energy range of 15 keV to 15 MeV.
