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

Results of simulating the shielding performance of the first 98 chemical elements against trapped particles on GTO.<br> The particle spectra are 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. 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 units of kRad per month.<br> Column E: ionizing dose due to protons in units of kRad per month.<br> Column F: Absolute statistical error in the proton dose due to the statistical nature of the Monte-Carlo simulation in units of kRad per month. <br> Column G: Total ionizing dose from electrons and protons in units of kRad per month.<br> Column H: Absolute statistical error in the total ionizing dose due to the statistical nature of the Monte-Carlo simulation in units of kRad per month. <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. All dose values are rounded according to their uncertainty.
