Radiological Characterization Studies for the CNGS Dismantling
No full textA comprehensive study of the radiological CNGS (CERN Neutrinos to Gran Sasso Experiment) environment characterization is presented. It comprises the evaluation of the residual dose rates of the most relevant standalone beam line equipment, such as the target and horn, as well as overall dose levels in the cavern before and after dismantling. Furthermore, the radionuclide inventories of the main objects to be dismantled were calculated by the Monte Carlo FLUKA code and ActiWiz. The latter is particularly important for transport and waste management. Moreover, we present benchmarking measurements of residual dose rates in the experimental cavern, staying in good agreement with simulation predictions. Additional measurements, as well as FLUKA and ActiWiz studies, allowed for assessing the concrete composition of the cavern’s walls and floor and the shielding blocks. The resulting refined composition allowed for evaluating more precisely the radionuclide inventories and residual dose rates expected before and after the dismantling in the CNGS target area. This was particularly important for the evaluation of the dismantling cost and the substantial savings due to the reusage of the majority of the concrete blocks. Finally, contamination measurements in the accessible parts of the area also are included. All the results discussed are crucial for determining the requirements, planning, and costs of the CNGS dismantling
FLUKA and ActiWiz benchmark on BDF materials
No full textThis note describes the FLUKA and Actiwiz benchmark with gamma spectroscopy results of various material samples, which were irradiated during the Beam Dump Facility (BDF) prototype target test in the North Area of the Super Proton Synchrotron (SPS) at CERN. The samples represent most of the materials that will be used in the construction of the BDF facility

FLUKA-Geant4 comparison for the muon flux experiment in the H4 beamline
No full textThe FLUKA - Geant4 comparison for the the muon flux experiment is reported. The experiment was performed in 2018 on the H4 400 GeV/c proton beamline to measure the muon flux emanating from a SHiP replica target. Good agreement between the two Monte Carlo simulations was found, in the low momentum and low transverse momentum range the agreement is at the level of 20%, while in the tails the disagreement is at maximum of a factor ∼3. These results suggest to reduce the safety factor for future BDF/SHiP facility radiation calculations from 5 (old recommended value) to 3 (new value)
FLUKA simulations of neutrino-induced effective dose at a Muon Collider
No full textDuring the operation of a muon collider in an underground tunnel, most circulating muons decay into an electron (or positron) and a neutrino-antineutrino pair, resulting in a narrow disk of high-energy neutrinos emitted radially in the collider plane and emerging on the Earth’s surface at distances of several km. Thus, dedicated studies are required to assess any potential radiation protection risks to the public due to the interaction of such neutrinos near the surface. This work presents a set of FLUKA Monte Carlo simulations aimed at characterizing the radiation showers generated by the interactions of high-energy neutrinos from TeV-scale muon decays in a reference sample of soil. The results are expressed in terms of effective dose in soil at different distances from the muon decay, quantifying the peak dose and the width of the radiation cone, for beam energies of 1.5 TeV and 5 TeV. The implications of these results for realistic muon collider scenarios are discussed, along with possible methods to mitigate the local neutrino flux
Integration Studies and Beam Physics for the Project of the NA60+ Heavy-Ion Experiment at CERN
No full textNA60+ is a fixed target experiment proposed in the framework of the Physics Beyond Colliders programme at CERN. It aims to precisely measure the hard and electromagnetic probes in nuclear collisions. Initially proposed for the underground cavern ECN3 with very high beam intensities, the experiment now foresees a location in the EHN1 surface hall which was shown to have a limited impact on the physics performance in spite of a significant reduction of beam intensity and detector size. The potential installation and operation of the experiment with the ion beams from the Super Proton Synchrotron (SPS) has been examined regarding detector integration, beam physics, radiation protection and shielding requirements. The integration of the experiment is considered feasible and would require a significant reconfiguration of the zone in regard to shielding and layout. The first estimate for the integration cost is 1.4 MCHF
