Handbook of SRNIEL and Nuclear Stopping Power (and TNID Doses) Calculators for Elements and Compounds (for instance, semiconductors) with an extension to Electronic Stopping Powers, Restricted EnergyLosses, TID Doses and Solar Modulation Models for Cosmic Rays
Welcome to the relativistic screening (SR) treatment handbook Website. In these pages you can find information about physics process regarding the Screened Relativistic (SR) Calculator of the NonIonizing 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.
The notation of screened relativistic (SR) NIEL was introduced by Baur et al. (2014). It is treated in Sects. 11.3.1, 11.3.2 of Leroy and Rancoita (2016) and Sect. 2 of Baur et al. (2014). The SRNIEL is derived from the SR (screened relativistic) nuclear stopping power for electrons (e.g., see Sect. 2.4.3 of Leroy and Rancoita (2016)) and the SR nuclear stopping power for massive particle at relativistic energies (e.g., see Sect.2.2.2 of Leroy and Rancoita (2016)).
Furthermore in the SRNIEL website, based on the physics framework here illustrated, an online calculator for the nuclear stopping powers of electrons, protons, light and heavyions 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 SRNIEL website, there are calculators available also for i) the probability of generating energetic recoil nuclei, ii) for the estimates of recoil energy fractions deposited via ionizing and nonionizing processe  using two of the mostly employed analytical approximations of energy partition function  and iii) the electronic stopping power and ionizing dose.
The user can additionally access to calculators which allow one to obtains NIEL values and NIEL doses for neutrons in Si and GaAs absorbers, derived from ASTM72209 and ASTM72214 standards.
Registered users can access to SRNIEL web calculators i) in which it is implemented the Akkerman and Barak (2006) partition function and ii) to get NIEL doses 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. Additional nuclei available after version 4.6.0 are listed at this page. A critical discussion on the usage of 1 MeV neutron equivalent is also available.
At present, in the SRNIEL website, calculators for ionizing energy losses (and doses) of electrons, protons and ions are also available. Furthermore, the high energy extension of electronic stopping power (referred to as SRframework electronic stopping power) for elements and compounds is accessible. From version 6.3.0, the webcalculators on electronic stopping powers – regarding the energy lost by particles traversing a medium – are complemented by those on restricted energylosses to deal with both the energy deposited by incoming particles in absorbers and the approach to Fermi plateau at high energies. The corresponding long writeups are found among the topics treated in the current Physics Handbook inside the section on Electronic stopping power, restricted energy loss and Solar Modulation and Solar Modulation.
From version 6.4.2, the topics covered in the present physics handbook are enlarged by referring to those treated in related activities discussed within ASIF, HelMod and GeoMagSphere websites.
This project is part of the activities on going at the SRNIEL/ASIF/AMS02 Milano Bicocca group.
The implementation of SRNIEL treatment and derived SRNIEL calculators into ESA (European Space Agency) codes (e.g., SPENVIS, GRAS and Mulassis) is accomplished under ESA contract 4000116146/16/NL/HK with title "NonIonizing Energy Loss (NIEL) Calculation and Verification".
