The current web calculator allows one to obtain the residual spectral fluence or residual energy for protons and ions traversing a shielding material by exploiting the "SRIM Module.exe" (with an upper energy limit of 5 GeV/amu) included in SRIM 2013 code (SRIM Tutorials) - whose maximum available energy is 10 GeV/amu -, i.e., the used electronic stopping power tables are those provided by "SRIM Module.exe" code with a low energy limit of 1 eV.
EXAMPLE:
Copy and paste the data here to reproduce the following example.Protons spectral fluence during ESA Juice mission moderated by 50 mils of Al (0.3429 [g cm-2]):
Spectral fluence data are calculated with JOREM Model implemented in SPENVIS assuming a 4 sr solid angle exposure.
NOTE:
The lower energy limit is 1 eV
The higher energy limit is 5 GeV/nucleon
The default traversed path is that for 50 mils of Al
The lower limit of traversed path is equivalent to about 5 μm of Si (1.16x10-3 [g cm-2]), e.g., 0.96 cm in Dry Air at sea level with density equal to 1.20484x10-3 g/cm3 (as implemented in SRIM from ICRU-37 table 5.5).
Residual energies were obtained disregarding multiple scattering effect, i.e., directions of flight of emerging particles were unchaged with respect to those of impinging directions.
Target selection for the results obtained in the EXAMPLE section
Selection for Protons in Silicon:
Selection for Protons in GaAs:
Selection for Protons in Water Liquid:
In SRIM, gas targets are dealt differently from those solid. User can select the target as a gas only for following elemental targets: H, He, N, O, F, Ne, Cl, Ar, Kr, Xe, Rn.
