Energy limit Specifics and applicability
Urban any - Default model, approach, tuned to data,
used for LHC production.
Screened
Nuclear Recoil
p, ions < 100 MeV/A Theory based process, providing simulation of nuclear recoil
for sampling of radiation damage, focused on precise
simulation of effects for space app.
GoudsmitSaunderson
e+, e- < 1 GeV Theory based cross sections. EPSEPA code developed by
Penelope group, final state using EGSnrc method,
precise electron transport
Coulomb
scattering
any - Theory based single scattering model, uses nuclear form-
factors, focused on muons and hadrons
WentzelVI any - MSC for small angles, Coulomb Scattering for large angles,
focused on simulation for muons and hadrons.
Ion Coulomb
scattering
any - Model based on Wentzel formula + relativistic effects +
screening effects for projectile & target.
