Website latest update on February 14, 2020

Welcome to the SR-NIEL Calculator Website. In these pages you can find information about the Screened Relativistic (SR) Calculator of the Non-Ionizing Energy Loss of electrons, protons and ions passing through an absorber, generating displacement damages and, in case of semiconductors, introducing deep levels resulting from the Frenkel pairs created. NIEL doses (also termed "displacement damage doses") are also provided.

Furthermore a calculator for the nuclear stopping powers of electrons, protons, light- and heavy-ions is available. The calculations are carried out based on the screened relativistic treatment for (elastic) Coulomb interactions on nuclei from low up to ultra relativistic energies.

In the present website version, a calculator for the probability of generating energetic recoil nuclei is also available. From version 1.5.2, additionally, the estimates of recoil energy fractions deposited via ionizing and non-ionizing processes are accessible using two of the mostly employed analytical approximations of energy partition function.
From version 2.0 the electronic stopping power and ionizing dose calculator are also available.

From version 2.1 the current calculator allows one to obains NIEL  values and NIEL doses for neutrons in Si and GaAs absorbers, derived from ASTM-722-09 and ASTM-722-14 standards.

From version 3.0 registered users can access to SR-NIEL web calculators with additionally implemented Akkerman and Barak (2006) partition function; For information please contact This email address is being protected from spambots. You need JavaScript enabled to view it..

Currently, additional functionalities implemented into NIEL calculators for registered users are:

  • electron NIEL with Akkerman partition function;
  • proton and ion NIEL with Akkerman partition function;
  • NIEL dose calculators for neutrons and neutron spectral fluence in some elements (C, N, Si, Ga, As, from version 3.5.1 0, Al, P, In, Cd, Te, Ge, Zn, Se, Sb, from version 3.9 Cu, Hg, Pb, S, Sn, from version 3.9.2 B, Bi, Cl, Tl, from version 4.5.0 Li, Ti, Mn, Br, Sr, Nb, Mo, Ag, I, Ba, La, Eu, U and from version 4.6.0 also H, He, Be, F, Na, Mg, Ar, K, Ca, V, Cr, Fe, Co, Ni) and their compounds, using Robinson and Akkerman partition functions. The complete set of nuclei for neutron dose calculators was made avaible with version 5.0.0 and is illustrated at this page.
    Furthermore, a critical discussion on the usage of 1 MeV neutron equivalent is also available to registered users.

  • high energy extension of the electronic stopping powers of protons and ions with version 6.2.0

In addition, for registered users are available the following long write-ups:

  • NIEL for Electrons and Protons (with only Coulomb scattering and, also, including hadronic contribution) in Silicon employing Robinson and Akkerman partition functions;
  • NIEL dose calculation for neutron using Robinson and Akkerman partition functions;
  • comparison of Damage Functions obtained with Akkerman and Robinson Partition Functions for some compounds;
  • determination of the Damage Function at 1 MeV for Si and some compounds.

More pieces of information about sr-treatment are currently available from the website dedicated to the physics of displacement damage, due to neutron, proton, ion and electron interactions on nuclei.

At present, in the sr-niel website, calculators for ionizing energy losses (and doses) of electrons, protons and ions  are also available. In addition, from version 5.5 it is availabe a calculator to determine the residual spectral fluence for particles traversing a shielding material.

This project is part of the activities on going at the sr-niel/ASIF/AMS-02 Milano Bicocca group.

The implementation of SR-NIEL treatment and derived SR-NIEL calculators into ESA (European Space Agency) codes (e.g., SPENVIS, GRAS and Mulassis) is accomplished under ESA contract 4000116146/16/NL/HK with title "Non-Ionizing Energy Loss (NIEL) Calculation and Verification".

From version 3.0 the sr-niel website allows one to access to additional functionalities to be gradually implemented.

These additional features are no longer freely accessible, because the data are not yet published and are supposed to be available, at the moment, for scientific reasons only and/or collaborating scientists. These NIEL values can be revised as a result of ongoing scientific discussions. Thus, a motivated registration is needed to get use of them.

No registration page is currently available, but potentially interested users should contact us for their requests, by email (This email address is being protected from spambots. You need JavaScript enabled to view it.), specifying their institution and foreseen usage of the data.
The login formation  and password will be provided directly to the final user. Personal information used for the registration process will be treated according to GDPR european policy.

Currently, additional functionalities implenented into NIEL calculators for registered users are:

  • electron NIEL with Akkerman partition function;
  • proton and ion NIEL with Akkerman partition function;
  • NIEL dose calculators for neutrons and neutron spectral fluence in some elements (C, N, Si, Ga, As, from version 3.5.1 0, Al, P, In, Cd, Te, Ge, Zn, Se, Sb, from version 3.9 Cu, Hg, Pb, S, Sn, from version 3.9.2 B, Bi, Cl, Tl, from version 4.5.0 Li, Ti, Mn, Br, Sr, Nb, Mo, Ag, I, Ba, La, Eu, U and from version 4.6.0 also H, He, Be, F, Na, Mg, Ar, K, Ca, V, Cr, Fe, Co, Ni) and their compounds, using Robinson and Akkerman partition functions. The complete set of nuclei for neutron dose calculators was made avaible with version 5.0.0 and is illustrated at this page.

In addition, for registered users are available the following long write-ups:

  • NIEL dose calculation for neutron using Robinson and Akkerman partition functions;
