FLUKA is a general purpose Monte Carlo code able to describe the transport and interaction of any particle nucleus type in complex geometries over an energy range extending from thermal neutrons ultrarelativistic hadron collisions. It has many different applications accelerator design, detector studies, dosimetry, radiation protection, medical physics, space research. In 2019, CERN INFN, as copyright holders, together decided end their formal collaboration framework, allowing them henceforth...
The SHiP-charm project was proposed to measure the associated charm production induced by 400 GeV/c protons in a thick target, including contribution from cascade production. An optimisation run performed July 2018 at CERN SPS using hybrid setup. high resolution of nuclear emulsions acting as vertex detector complemented electronic detectors for kinematic measurements and muon identification. Here we present first results on analysis exposed run, which prove capability reconstructing proton...
This paper discusses an experimental study of the spallation reaction 27Al(p,3pn)24Na in Al foils exposed to 24 GeV c−1 protons, context monitoring intensity multi-GeV proton beams through foil activation techniques. Since this is sensitive secondary neutrons and other energetic hadrons, it important evaluate impact thickness on calculation beam intensity. effect determined experimentally using a stack varying thickness. The results are then compared Monte Carlo simulations.
Taking advantage of the heavy ion acceleration program, tests on radiation effects with Ultrahigh Energy (UHE) xenon beams (with > 5 GeV/nucleon) have been performed in several experimental areas CERN accelerator complex. Specifically, outcomes first UHE test campaign carried out at CHARM facility are presented and discussed this contribution. not requiring a previous modification samples or testing vacuum, owing to their large penetration range. The unique nature ions motivated study...
The present paper describes the new, original implementation of a point-wise neutron treatment that is made available with FLUKA v4.3-0 ( https://fluka.cern ). development based on pre-processed data libraries for Geant4 code https://cern.ch/geant4 was written from scratch in C++ and able to load information all databases (ENDF, JEFF, JENDL, CENDL, BROND), including materials S(α,β,T) nuclear binding effects.

Radiological characterization of components in accelerator environments is often required to ensure adequate radiation protection during maintenance, transport and handling as well for the selection proper disposal pathway. The relevant quantities are typical weighted sums specific activities with radionuclide-specific weighting coefficients. Traditional methods based on Monte Carlo simulations radionuclide creation-event or particle fluences regions interest scored then off-line production...
To devise an activation technique for characterizing mixed radiation fields, secondary particles from a copper target irradiated by 24 GeV/c protons were measured at the CERN High-energy AcceleRator Mixed field facility (CHARM).
