Shielding performance of the 98 first chemical elements against trapped particles on GTO

<p>The 1LayerElements.csv file contains the shielding performance results for the first 98 chemical elements against trapped particles in Geostationary Transfer Orbit (GTO).<br> The material properties are sourced from the Geant4 material database, with materials referenced by their Geant4 material database names<br> For elements that are gases under normal conditions, the liquified version from the Geant4 database is used if available, denoted by an &quot;l&quot; prefix (e.g., &quot;G4_lH2&quot;).<br> The particle spectra used for this simulation are provided in the files AE9500keV.mac and AP910MeV.mac.<br> The simulated geometry is provided in the file 1LayerElements.gdml<br> <br> The particle spectra were generated with the AE9/AP9 models on SPENVIS, with electron energies starting at 500 keV and proton energies starting at 10 MeV.<br> The simulation was performed with GRAS / Geant4 with the FTFP_BERT physics model using 4.3e+10 electrons and 1e+08 protons directed against slabs of shielding materials of 1.5 g/cm2 depth.<br> The ionizing dose is recorded in 0.5mm thick silicon plates behind the shielding plates.</p> <p>Column A: Z-number of the element.<br> Column B: Name of the material as referenced from the Geant4 material database.<br> Column C: Ionizing dose due to electrons in units of kRad per month.<br> Column D: Absolute statistical error in the electron dose due to the statistical nature of the Monte-Carlo simulation in kRad per month.<br> Column E: ionizing dose due to protons in kRad per month.<br> Column F: Absolute statistical error in the proton dose in kRad per month.&nbsp;<br> Column G: Total ionizing dose from electrons and protons in kRad per month.<br> Column H: Absolute statistical error in the total ionizing dose in kRad per month.&nbsp;<br> Column I: Relative statistical error of the total ionizing dose in per cent.<br> Column J: Rank of the material sorted from lowest total ionizing dose to highest.<br> Column K: Rank of the material sorted from lowest electron dose to highest.<br> Column L: Rank of the material sorted from lowest proton dose to highest.</p> <p>All dose values are rounded according to their uncertainty.</p>
