Notably, as the permeation cycles increased, the permeability curve exhibited an abnormal-to-normal transformation phenomenon. Increasing deuterium pressure at this stage could restore the permeability to its abnormal state. By comparing the permeation cycles of niobium foils with different oxidation degrees at 1023 K, we found that surface oxide thickness did not affect the abnormal phenomenon but reduced the diffusion coefficient of deuterium during initial permeation. Additionally, we observed that the permeation flux was proportional to the square root of pressure, indicating that diffusion still controlled permeation. After the deuterium loading, the abnormal phenomenon of the 1st permeation disappeared, and the diffusivity of deuterium in niobium decreased. The results suggested that the abnormal phenomena in 1st permeation were primarily caused by the irreversible defects resulting from the interaction between niobium and deuterium in the bulk phase and were not related to the surface effect. The pressure, concentration, and temperature of deuterium in the bulk phase accelerated the interaction between niobium and deuterium and promoted the transition of deuterium in niobium to abnormal permeation. These research findings hold significant implications for the application of niobium as a hydrogen isotope separation and purification material.</p></div>","PeriodicalId":634,"journal":{"name":"Journal of Fusion Energy","volume":"43 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141641257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enhance the accuracy of conventional tomography algorithms, a Bayesian-based non-stationary Gaussian processes tomography as the emission model has been implemented in the soft X-ray diagnostics of the HL-2 A tokamak. However, the Bayesian tomography method is time-consuming and has difficulty achieving quick reconstructions for tokamak. In this work, neural networks have been trained and tested on a large set of sample tomograms based on experimental SXR data and Bayesian tomography method. The trained neural networks can predict the reconstructions of emission profiles accurately, fast, and robustly to noise. In the future, it is possible to easily implement this algorithm on different diagnostics and fusion devices.</p></div>","PeriodicalId":634,"journal":{"name":"Journal of Fusion Energy","volume":"43 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141570943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
