 Full simulation and performance of a standard iron warm muon shield with tuned return yoke / Ferro-Luzzi, Massimiliano (CERN) /SHiP Collaboration Full simulation and performance of a standard iron warm muon shield with tuned return yoke CERN-SHiP-INT-2022-007.- Geneva : CERN, 2022

 A possible yokeless superconducting dipole for the SHiP muonshield / Koratzinos, m (Massachusetts Inst. of Technology (US)) ; Van Herwijnen, Eric (National University of Science and Technology "MISIS" (RU)) /SHiP collaboration We describe the use of a superconducting Canted Cosine Theta (CCT) magnet as an alternative for the baseline warm magnet for the muon shield. The conductor of the CCT magnet ensures an excellent field quality with a gentle return field. [...] CERN-SHiP-INT-2022-006.- Geneva : CERN, 2022

 Preliminary exploration of a superconducting muon shield / Ferro-Luzzi, Massimiliano (CERN) /SHiP collaboration The current baseline design of the muon shield is based on warm magnets. This note exposes first muon background simulation results of a preliminary exploration into the possibility to use superconducting magnets. [...] CERN-SHiP-INT-2022-005.- Geneva : CERN, 2022

 Normal-conducting muon shield with standard yoke iron and tuned return yoke ; first performance assessment / Wertelaers, Piet (CERN) /SHiP collaboration A muon deflecting complex with only warm magnets has always been the baseline. But here, we have a first look at a concept based on traditional engineering, i.e [...] CERN-SHiP-INT-2022-004.- Geneva : CERN, 2022 Fulltext: PDF;

 Muon shield concept based on superconducting magnet and tuned iron return yoke / Wertelaers, Piet (CERN) /SHiP collaboration Deterministic muon tracing seems to indicate that good deflection performance can be obtained from a train of magnetized Hadron Stopper and superconducting Main Magnets, the second of which is of reversed polarity. However, the wide range of low-momentum muon start rapidities, forces us into a wide and high design.. CERN-SHiP-INT-2022-003.- Geneva : CERN, 2022 Fulltext: PDF;

 Deterministic trace computation of charged particle in three dimensions / Wertelaers, Piet (CERN) /SHiP collaboration Establishing the curved trajectory of a charged particle in a magnetic field, becomes a stochastic affair as soon as the particle interacts with material, and then, Monte Carlo simulation is the traditional computational method. Here, we develop a deterministic competitor. [...] CERN-SHiP-INT-2022-002.- Geneva : CERN, 2022 Fulltext: PDF;

 How the distance of the cavern walls affects the background rates / Ferro-Luzzi, Massimiliano (CERN) /SHiP collaboration The muon shield of the Beam Dump Facility splits the spurious muons from the target into two prominent plumes left and right of the SHiP experiment. A large fraction of these muons interact with the cavern walls. [...] CERN-SHiP-INT-2022-001.- Geneva : CERN, 2022 main document: PDF;

 Interpolating magnetic field data onto a three-dimensional regular grid / Wertelaers, Piet (CERN) /SHiP collaboration Magnetic field data do not always exist on the exact locations of the regular grid used in physics simulations, in which case interpolation must be performed. The “general” method makes no a priori assumptions of the nature of the primary data ; they can be measurements. [...] CERN-SHiP-INT-2021-005.- Geneva : CERN, 2021 2022-02-15 version: PDF;

 Multiple scattering: variance of the transverse offset after an arbitrary number of media / Ferro-Luzzi, Massimiliano (CERN) /SHiP collaboration When a relativistic charged particle traverses a medium, it undergoes multiple (small angle) scattering processes. In the 2-dimensional case (planar), such process is often simulated using two uncorrelated Gaussian-distributed random numbers to generate the correlated transverse deflections (offsets and angles) through a medium.

 BDF/SHiP muon deflection - First ideas about an integrated apparatus with superconducting main magnet / Wertelaers, Piet (CERN) ; Ferro-Luzzi, Massimiliano (CERN) /SHiP Collaboration An order 20 m long superconducting magnet would largely suffice to deflect the highest-energy Target-produced muons, and moreover, it could lodge part of the Scattering Neutrino Detector, thus circumventing the need of a separate magnet. The idea of a preceding magnetized Hadron Stopper is kept. [...] CERN-SHiP-INT-2021-003.- Geneva : CERN, 2021 Fulltext: PDF;
