EXAMPLE:
Spectral number of SEE as a function of ionization energy deposited by recoil nuclei for a fluence of 1e15 protons/cm2 of 100 MeV in 10 μm of Si (2.33e-3 g cm-2):

NOTE:
  • Emax should be estimated by the user taking into account the effective size of the device. The default value Emax=25 MeV corresponds to the effective maximum ionizing energy deposited and absorbed from the recoil silicon nucleus (with a total range of about 9.5-10.0 μm in silicon medium) inside the device medium due to its finite size.
  • The sr-treatment has accuracy of about some percent at 50-200 keV/nucleon (see Sect 2.2.2 in [Leroy and Rancoita (2016)]).
  • The calculator provides both the total number of SEE due to recoil and the spectral recoil probability.
