The Liège Intranuclear Cascade model, INCL, has been originally developed to describe spallation reactions,
i.e. nucleon induced collisions in the 100 MeV - 3 GeV energy range. Extensive comparisons with
experimental data covering all possible reaction channels have shown that its last version, INCL4, coupled
to the ABLA07 de-excitation code from GSI, is presently one of the most reliable models in its domain.
The model has been implemented into several high-energy transport codes allowing simulations in a wide
domain of applications. Recently, efforts have been devoted to extending the model beyond its strict limits
of validity, i.e. at energies below 100 MeV and above 3 GeV and for light-ion (up to oxygen) induced reactions.
In this paper, these extensions will be presented, comparisons with experimental data will be shown
and impact on applications will be discussed. Examples of simulations performed for spallation targets
(ESS and ISOLDE) with the model implemented into MCNPX and in the domain of medical applications
with GEANT4 will be shown.

Beam-machine Interaction at the CERN LHC

The radiation field generated by a high energy and intensity accelerator is of concern in terms of element
functionality threat, component damage, electronics reliability, and material activation, but provides also
signatures allowing to monitor the actual operation conditions. The shower initiated by an energetic hadron
involves many different physical processes, down to slow neutron interactions and fragment de-excitation,
which need to be accurately described for design purposes as well as to interpret operation events. The
experience with the transport and interaction Monte Carlo code FLUKA at the Large Hadron Collider
(LHC), operating at CERN with 4 TeV proton beams (and equivalent magnetic rigidity Pb beams) and
approaching nominal luminosity and energy, is presented. Design, operation and upgrade challenges are
reviewed in the context of beam-machine interaction account and relevant benchmarking examples based
on radiation monitor measurements are shown.
