Hence, a single-photon emission computed tomography (SPECT) detector equipped with the scintillator has excellent X-ray and <inline-formula> <tex-math>$gamma $ </tex-math></inline-formula>-ray detection efficiency and a high light yield (LY). The feasibility of utilizing the TLC crystal coupled with a silicon photomultiplier (SiPM) was investigated for a compact SPECT detector. The TLC crystal (Ø<inline-formula> <tex-math>$8times 2$ </tex-math></inline-formula> mm) coupled with a one-channel SiPM (<inline-formula> <tex-math>$6.07times 6.07$ </tex-math></inline-formula> mm2) was used. Electrical characteristics of the SiPM were used for optimizing the operating voltage and dynamic range. The <inline-formula> <tex-math>$gamma $ </tex-math></inline-formula>-rays’ energy spectra of 133 Ba, 241Am, and 152 Eu were obtained. The SiPM outputs were digitized utilizing a data acquisition (DAQ) system. The breakdown voltage of the SiPM was measured to be 24.8 V. The operating voltage was fixed as 29.8 V by comparing energy resolutions for different operating voltages under 81-keV <inline-formula> <tex-math>$gamma $ </tex-math></inline-formula>-ray excitation from a 133Ba radioactive source. The linearity of the SiPM was measured to be within 3.7% for up to 8500 incident photons. Owing to the high LY of the TLC crystal and the dynamic range of SiPM, the best energy resolution of the TLC crystal was achieved to be 8.7% full-width-half-maximum at 121.7-keV <inline-formula> <tex-math>$gamma $ </tex-math></inline-formula>-ray at the voltage of 29.8 V. The TLC crystal coupled with SiPM is expected to be utilized for the development of compact SPECT detectors. It can replace conventional photomultiplier detectors and attain a good image quality, comparable to that of a solid-state detector in the SPECT system.","PeriodicalId":13406,"journal":{"name":"IEEE Transactions on Nuclear Science","volume":"72 5","pages":"1828-1832"},"PeriodicalIF":1.9,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results highlight that: 1) high-energy neutron (HEn) upset rates continue to dominate the total soft error rate (SER) in terrestrial radiation environments and 2) SERs continue to benefit from technology scaling. Accelerated testing projections demonstrate a <inline-formula> <tex-math>$sim 20times $ </tex-math></inline-formula> reduction in bit-level SERs between 45- and 10-nm SRAM cells of the same type. Results obtained from a three-year real-time test campaign are discussed and compared to accelerated testing projections and previous real-time testing results published by this team. Interestingly, the 10-nm real-time testing results show a consistent underestimation compared to projections obtained from accelerated beam testing. It is speculated that the scattering and absorption of HEns in the real-time testing setup are the main reasons for the observed discrepancy. Finally, single event upset (SEU) data are compared with selected space-weather databases, specifically gamma ray bursts (GRBs), ground level enhancements (GLEs), and solar energetic proton (SEP) events collected by the Geostationary Operational Environmental Satellites (GOES). No clear correlation is observed.","PeriodicalId":13406,"journal":{"name":"IEEE Transactions on Nuclear Science","volume":"72 5","pages":"1768-1778"},"PeriodicalIF":1.9,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leveraging the Geant4 toolkit, the theoretical models of BEDFs are established. When the thickness of the bismuth deposited layer is <inline-formula> <tex-math>$5~mu $ </tex-math></inline-formula>m, the energy deposited in the core is reduced by 49.66% (5.91 MeV). The energy deposited in the core is reduced by 19.7% (1.06 MeV) when Bi3+ ions’ concentration is 10 wt%. EDF, BEDF1, and BEDF2 were irradiated with 0.3-, 0.5-, 0.8-, and 1.5-kGy doses of Co60 source. After radiation with 1.5 kGy, radiation-induced absorption (RIA) of BEDF2 at 1300 nm is 20.31% (1.01 dB/m) lower than that of BEDF1. The radiation induced gain variation (RIGV) and fluorescence lifetime of EDF are decreased with the increase in irradiation dose, while the RIGV and lifetime of BEDF1 and BEDF2 both increased initially and then decreased linearly. The normalized gain of BEDF2 is increased by up to 1.08 dB/m after 0.5-kGy radiation. Bismuth ions in the fiber core improve the radiation resistance of the fiber, and those deposited on the fiber surface further improve the radiation resistance. The research results have reference value and application potential in radiation environment detection and space satellite positioning.","PeriodicalId":13406,"journal":{"name":"IEEE Transactions on Nuclear Science","volume":"72 5","pages":"1779-1789"},"PeriodicalIF":1.9,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
