The effects of irradiation on the memristive performances are studied through 60Co <inline-formula> <tex-math>$gamma $ </tex-math></inline-formula>-ray irradiation experiments. The effect of irradiation on the image recognition accuracy of the neural network based on the memristive synapse crossbar array is predicted. The results show that the devices maintained good conductance update linearity under irradiation. When the 60Co <inline-formula> <tex-math>$gamma $ </tex-math></inline-formula>-ray irradiation reaches 1 Mrad(Si), the nonlinearity (NL) of conductance update only increases from 0.096 to 0.163, and the image recognition accuracy of the memristor neural network decreases by about 2% (from 91% to 89%). The initial value of oxygen defect content in HfOx resistive materials after Al doping modification is relatively high (36%), which can explain why irradiation has little effect on conductance update linearity and recognition accuracy. These results suggest that the Au/Al:HfOx/TiOx/Ti memristors show good radiation resistance under 60Co <inline-formula> <tex-math>$gamma $ </tex-math></inline-formula>-ray irradiation, which makes them promising candidates for artificial synapses in space applications.","PeriodicalId":13406,"journal":{"name":"IEEE Transactions on Nuclear Science","volume":"72 3","pages":"866-874"},"PeriodicalIF":1.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637781","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}

Previous studies have provided iterative simulation algorithms; however, these algorithms are time-consuming and inefficient and do not directly explain how the detector parameters and neutron flux affect the space electric field and its evolution. Therefore, for the first time, we propose an analytical method to calculate the space charge effect. This method provides an analytical expression for the evolution of the space charge distribution, significantly improving computational efficiency. The analytical expression reveals that the space charge distribution is proportional to the neutron flux density, bulk resistivity, and dielectric constant of the insulator, which confirms the results from the previous numerical studies. Moreover, this work presents a method for calculating the time constant of the space charge evolution for the first time. Based on this time constant, the electric field equilibrium time can be predicted, providing guidance for presetting the time step in iterative calculations. Comparisons between the analytical predictions and iterative calculations were conducted for both cobalt SPND (Co-SPND) and rhodium SPND (Rh-SPND). The results from the analytical model and from the iterative model are consistent, demonstrating the accuracy of this proposed analytical method.","PeriodicalId":13406,"journal":{"name":"IEEE Transactions on Nuclear Science","volume":"72 3","pages":"807-815"},"PeriodicalIF":1.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637838","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}

This challenge is further compounded by issues related to system integration, power consumption, and cost efficiency. To address these challenges, this study proposes two novel multiplexing methods based on Eulerian circuits. Mathematical calculations indicate that with n electronic channels, up to <inline-formula> <tex-math>$n times (n-1)/2 - (n - 2)/2 + 1$ </tex-math></inline-formula> detector channels can be read out, where n is even. Three types of multiplexing circuits were designed, implemented, and tested in combination with micromesh gaseous structure (Micromegas) detectors. Experimental results demonstrate that for a multiplexing circuit with a factor of 8, the spatial resolution remains comparable to the direct readout method, while achieving a detection efficiency exceeding 94%. For a circuit with a multiplexing factor of 16, although the spatial resolution shows a slight degradation, the detection efficiency remains above 93.6%. These results demonstrate that the proposed multiplexing methods can significantly reduce the number of readout channels while maintaining an acceptable level of spatial resolution and detection efficiency. These findings highlight the potential of the proposed multiplexing techniques for applications in fields requiring high-resolution and cost-effective detector systems, such as cosmic-ray muon imaging.","PeriodicalId":13406,"journal":{"name":"IEEE Transactions on Nuclear Science","volume":"72 3","pages":"765-772"},"PeriodicalIF":1.9,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645209","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}
