Since there is no elastic element able to move under low and high pressures, there is a serious limitation to measuring low and high pressures concurrently. This paper proposes an innovative mechanism for measuring high and low pressures concurrently. In the proposed mechanism, a variable-thickness diaphragm and a protective part were used to measure a broad range of pressures. The proposed mechanism was manufactured and the accurate pressure source was used to test the behavior of the mechanism under different pressures. Using this configuration raised the sensitivity and accuracy of high-range pressure sensors, and increased the turndown ratio to 1500 by employing a new elastic element. Employing this mechanism in pressure sensors leads to use one pressure sensor for measuring a broad range of pressure instead of using several distinct sensors.","PeriodicalId":12864,"journal":{"name":"High Pressure Research","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135901060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The investigations are conducted on the pre-stressing dies using the equal tensile stress (ETS), equal shear stress (ESS), and constant tangential stress (CTS) winding approaches. First, it is determined theoretically what the maximum cavity pressure and the necessary number of winding layers would be. The shear stresses of the cylinder and the support ring, the displacements of the cylinder, and the axial stresses of the steel wire layer are then examined using the finite element method. The results of the theoretical calculation and simulation are compared and discussed. The findings indicate that the ESS winding is a better option.KEYWORDS: Ultra-high pressuresteel wire windingfinite elementprestress Disclosure statementNo potential conflict of interest was reported by the author(s).Data availabilityThe data that support the findings of this study are available from the corresponding author upon reasonable request.Additional informationFundingThis research is supported by the National Science Foundation of China under grant number 51605007 and the National Science Foundation of Anhui Province under grant number1708085QE126, and we sincerely appreciate them.","PeriodicalId":12864,"journal":{"name":"High Pressure Research","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135901708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The processing of these X-radiographic images to determine bulk sample strain is one of the limiting factors to making measurements closer to the strains and strain-rates that occur during mantle convection or the passage of seismic waves. Typically, sample deformation in these experiments is tracked by the displacement of high-contrast marker foils in X-radiographs. X-radiographs are treated individually or pairwise in a multi-step process that tracks the displacement of marker foils during experiments. Here I develop a new algorithm, FoilTrack, that treats all the X-radiographic observations in a single-step process, resulting in improved accuracy and consistency of length changes determined from X-radiographic images, as well as providing more realistic parameter uncertainty. The improvements are demonstrated using data from small-strain sinusoidal deformation experiments.","PeriodicalId":12864,"journal":{"name":"High Pressure Research","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48734351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The compressibility is identical in both media. At the initial stage the compression proceeds mainly within the plane (xy) and less along the z-axis; above 3 GPa the compression becomes almost isometric. Within the whole pressure range there are no signs of the symmetry lowering. The main pressure-induced effect on the tetrahedral layer consists in a cooperative rotation of the 4-fold rings, which provides the structure compression within the (xy) plane. The compression along the z-axis proceeds through the shortening of the interlayer distance, whereas the thickness of silicate layer remains almost unchanged.","PeriodicalId":12864,"journal":{"name":"High Pressure Research","volume":"1 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42677215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Experimenters typically rely on the availability of robust data collection and analysis at a beamline, but this has become increasingly difficult, especially with the introduction of multi-element detectors that generate complex, multi-dimensional data sets. These data sets have energy resolution, and they can also be resolved in relation to sample position, diffraction angle, or different external stimuli. We report a new Python-based graphical program, hpMCA, for EDXD data collection and analysis that streamlines the experimental process for the beamline users. The program features a user-friendly interface, capability for online viewing and analyzing data from multi-element energy-dispersive detectors, and includes features useful for working with samples under high pressure and/or high temperature, such as crystal phase identification, real-time unit cell lattice refinement, and pressure determination based on an equation of state.","PeriodicalId":12864,"journal":{"name":"High Pressure Research","volume":"43 1","pages":"175 - 191"},"PeriodicalIF":2.0,"publicationDate":"2023-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46568825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
