The main purpose of the facility is to deliver neutron-rich radioactive beams with a range of mass between 60 and 160 amu produced as fission products originated within a Uranium Carbide (UC<sub>x</sub>) target impinged by high energy protons (40–70 MeV). In the last few years, the SPES group and their collaborators have focused on multiple aspects: development of various ISOL targets, ion sources, a high-power beam dump, versatile Front-End designs, primary proton beam and RIB diagnostics, design of beam optic components, and remote target handling. The development and optimization of ionization sources represents one of the most important R&D activities. The collaboration between SPES and ISOLDE (CERN) groups has enabled the evaluation of the performances of a novel FEBIAD ion source taking advantage of the ISOLDE off-line Front-End. In this paper, the results of efficiency and transversal emittance measurements of the new SPES FEBIAD ion source are presented and discussed. Particular attention is dedicated to the description of the experimental setup and to the comparison of experimental data with simulation to promote the reproducibility of the experimental tests with other types of sources.</div></div>","PeriodicalId":19380,"journal":{"name":"Nuclear Instruments & Methods in Physics Research Section B-beam Interactions With Materials and Atoms","volume":"563 ","pages":"Article 165688"},"PeriodicalIF":1.4,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143696091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Critical shielding parameters, including linear attenuation coefficients, half-value layers, equivalent atomic numbers, and transmission factors, were analyzed using Monte Carlo simulations and other computational methods. Among the investigated samples, the 16Nb2B glass exhibited exceptional performance, with an LAC of 7.0613 cm<sup>−1</sup> at 0.01 MeV, outperforming the 40La14B glass by 29 %. Its HVL was as low as 0.003 cm at 0.015 MeV and 1.725 cm at 0.662 MeV, marking a considerable reduction compared to steel-magnetite concrete. Moreover, the deposited energy in the air surrounding 16Nb2B was 1.18 × 10<sup>-4</sup> MeV/g, reflecting reductions of 59.9 % and 56.1 % compared to Boron Carbide and cement-bitumen mixtures, respectively. The TF values for 16Nb2B consistently showed superior attenuation, with reductions of 6.6 % at 3.0 cm thickness and 0.662 MeV compared to steel-magnetite concrete. It can be concluded that the 16Nb2B glass not only provides outstanding optical transparency properties but also provides better radiation shielding properties, making it a promising candidate for applications in medical imaging, nuclear facilities, and radioactive material transport.</div></div>","PeriodicalId":19380,"journal":{"name":"Nuclear Instruments & Methods in Physics Research Section B-beam Interactions With Materials and Atoms","volume":"563 ","pages":"Article 165683"},"PeriodicalIF":1.4,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143620372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One promising approach for describing the evolution of defects involves using chemical rate theory. We aim to study the influence of irradiation and external conditions on the evolution of radiation point defects in nanocrystalline fcc metals. We used nanocrystalline nickel for which we know the parameters as a model fcc metal. The approach can be applied to nanoparticles as well. By solving the non-stationary equations, possible dependencies of defect concentrations on irradiation time, dose, temperature and nanoparticle size have been established. It was found that there are situations where the defect concentration increases with increasing grain (or particle) size, does not depend on size, is nonmonotonic with maximum, or decreases with an inverse dependence on size. This variability is ensured by the intensity of defect interactions at external boundaries, recombinations inside the grain (particle), temperature, time (dose), and irradiation regimes.</div></div>","PeriodicalId":19380,"journal":{"name":"Nuclear Instruments & Methods in Physics Research Section B-beam Interactions With Materials and Atoms","volume":"563 ","pages":"Article 165674"},"PeriodicalIF":1.4,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143620371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
