SR-NIEL – 7

Screened Relativistic (SR) Treatment for NIEL Dose

Nuclear and Electronic Stopping Power Calculator

(version 10.14)

Proton High AMS02 small

The current web calculator for stopping powers is a real time implemetation of 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:
Electronic Stopping Power for Protons in Silicon:

Electronic Stopping Power for Protons in GaAs:

Electronic Stopping Power for Protons in Water Liquid:

NOTE:
  • Output table and graph include the electronic stopping power in units of Mev cm2/g (i.e., the mass electronic stopping power).
  • The lower energy limit is 1 eV
  • The higher energy limit is 5 GeV/nucleon
  • 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.
  • FINAL REMARK:
  • In the present electronic stopping power to dose converter, the energy lost by the incoming particle is assumed to be fully absorbed by the medium - for instance, the medium is supposed to to be thick enough to fully absorb the kinetic energy of emitted delta rays - and the particle energy is almost constant while traversing the absorber.
