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. 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. 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. The ionizing dose is recorded in 0.5mm thick silicon plates behind the shielding plates. Column A: Z-number of the element. Column B: Name of the material as referenced from the Geant4 material database. Column C: Ionizing dose due to electrons in units of kRad per month. 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. Column E: ionizing dose due to protons in units of kRad per month. 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. Column G: Total ionizing dose from electrons and protons in units of kRad per month. 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. Column I: Relative statistical error of the total ionizing dose in per cent. Column J: Rank of the material sorted from lowest total ionizing dose to highest. Column K: Rank of the material sorted from lowest electron dose to highest. Column L: Rank of the material sorted from lowest proton dose to highest. All dose values are rounded according to their uncertainty
