Track reconstruction and matching between emulsion and silicon pixel detectors for the SHiP-charm experiment

In July 2018 an optimization run for the proposed charm cross section measurement for SHiP was performed at the CERN SPS. A heavy, moving target instrumented with nuclear emulsion films followed by a silicon pixel tracker was installed in front of the Goliath magnet at the H4 proton beam-line. Behind the magnet, scintillating-fibre, drift-tube and RPC detectors were placed. The purpose of this run was to validate the measurement's feasibility, to develop the required analysis tools and fine-tune the detector layout. In this paper, we present the track reconstruction in the pixel tracker and the track matching with the moving emulsion detector. The pixel detector performed as expected and it is shown that, after proper alignment, a vertex matching rate of 87% is achieved.Peer Reviewe

SND@LHC: The Scattering and Neutrino Detector at the LHC

SND@LHC is a compact and stand-alone experiment designed to perform measurements with neutrinos produced at the LHC in the pseudo-rapidity region of ${7.2 < \eta < 8.4}$. The experiment is located 480 m downstream of the ATLAS interaction point, in the TI18 tunnel. The detector is composed of a hybrid system based on an 830 kg target made of tungsten plates, interleaved with emulsion and electronic trackers, also acting as an electromagnetic calorimeter, and followed by a hadronic calorimeter and a muon identification system. The detector is able to distinguish interactions of all three neutrino flavours, which allows probing the physics of heavy flavour production at the LHC in the very forward region. This region is of particular interest for future circular colliders and for very high energy astrophysical neutrino experiments. The detector is also able to search for the scattering of Feebly Interacting Particles. In its first phase, the detector will operate throughout LHC Run 3 and collect a total of 250 $\text{fb}^{-1}$

Measurement of the muon flux from 400 GeV/c protons interacting in a thick molybdenum/tungsten target

The SHiP experiment is proposed to search for very weakly interacting particles beyond the Standard Model which are produced in a 400 GeV/c proton beam dump at the CERN SPS. About 1011 muons per spill will be produced in the dump. To design the experiment such that the muon-induced background is minimized, a precise knowledge of the muon spectrum is required. To validate the muon flux generated by our Pythia and GEANT4 based Monte Carlo simulation (FairShip), we have measured the muon flux emanating from a SHiP-like target at the SPS. This target, consisting of 13 interaction lengths of slabs of molybdenum and tungsten, followed by a 2.4 m iron hadron absorber was placed in the H4 400 GeV/c proton beam line. To identify muons and to measure the momentum spectrum, a spectrometer instrumented with drift tubes and a muon tagger were used. During a 3-week period a dataset for analysis corresponding to (3.27±0.07) × 1011 protons on target was recorded. This amounts to approximatively 1% of a SHiP spill

Brazilian Cases And The Debate About Risk Communication And Governance In Areas Contaminated By Lead [experiências Brasileiras E O Debate Sobre Comunicação E Governança Do Risco Em áreas Contaminadas Por Chumbo]

This investigation focused on lead contamination case studies in Brazil. The situations studied involve communities living in Santo Amaro da Purificação and Adrianópolis, in the northeast and south of Brazil, respectively. These communities have all had to live with environmental contamination and human exposure to lead as a consequence of industrial, mining and processing activities that were conducted by the same company for decades in a manner inconsistent with modern mining and industrial standards, with little control of environmental and human health impacts. The investigation sought to analyze the strategies of risk communication to local people, and to evaluate their engagement in risk management. The methodological approach included the analysis of newspaper articles, and interviews conducted with different stakeholders, such as residents, journalists, researchers and authorities. The results indicated the need to promote public involvement in the debate and in the decision-making process. The results also confirmed the hypothesis that associative models (represented by local neighborhood associations, for instance) are important for promoting and eliciting public participation in risk management.172337349Alcântara, C.H., Usos Y Abusos Del Concepto De Gobernabilidad (1998) International Social Science Journal, (155). , http://www.diba.es/fl/fitxers/pf-050.pdf, Unesco.

Communication And Risk Governance: The Brazilian Experience In Areas Contaminated By Lead [comunicação E Governança Do Risco: A Experiência Brasileira Em áreas Contaminadas Por Chumbo]

Considering the contemporary debate on themes involving risk situations in contaminated areas, some relevant concepts about risk communication and risk governance are discussed in this article. A critical analysis of two case studies on communities exposed to lead Brazil is presented: in Adrianópolis (Ribeira Valley, State of Paraná) and Santo Amaro da Purificação (State of Bahia).132283297Alcântara, C.H., (2008) Usos y abusos del concepto de governabilidad 1998, , http://www.diba.es/fl/fitxers/pf-050.pdf, Disponível em: Acesso em: 9 julAshford, N.A., Rest, K.M., (1999) Public participation in contaminated communities, , http://web.mit.edu/ctpid/www/tl/TL-pub-PPCC.html#ab, Center for Technology, Policy and Industrial Development, Massachusetts Institute of Technology, Cambridge, Massachusetts, Disponível em: Acesso em: 6 ago. 2008Boholm, A., Editorial: new perspectives on risk communication: uncertainty in a complex society (2008) Journal of Risk Research, 11 (1-2), pp. 1-3(2008) Avaliação de risco à saúde humana por metais pesados: Santo Amaro da Purificação, Bahia, , http://portal.saude.gov.br/portal/saude/area.cfm?id_area=1257, Brasil.

Participative Risk Communication As An Important Tool In Medical Geology Studies

Risk situations related to brownfield sites, contaminated lands and groups exposed to toxic substances are common in South America. In some of these situations, there is a lack of institutional response to the risks and consequences coupled with a failure to communicate the risks to those affected. Drawing on empirical research in 4 South American communities exposed to lead contamination, we investigated which strategies of risk communication (RC) have been used by researchers to communicate the risks of contamination, and the possible impacts of these strategies. Considering that risk situations of contaminated lands are characterized by uncertainty/strain/controversy, and that their residents are in a collective stress situation because of the physical conditions in their neighborhood and possible impacts on their health, in our study we argue for the need of participative RC in medical geology studies. The participative RC is based on cultural/social elements, trust, open dialogue and collective learning process to implement policies for mitigating risks and for a sustainable future. However, the analysis of these cases suggests that the efforts of RC have focused only on information transmission and public persuasion. We noticed that RC did not promote an open dialogue, or any discussion about the life styles of locals, which gave the impression that research results have not been properly released, and therefore, the general understanding (by assorted actors) is that environmental/health research is not being undertaken for the public good. These experiences endorse a need for a debate about participative RC among medical geology researchers. © 2012 Elsevier B.V.1313744Anderson, A., (1997) Media, Culture and Environment, , UCL Press Limited, LondonAtkinson, R., Flint, J., Accessing hidden and hard-to-reach populations: snowball research strategies (2001) Social Research Update, Guildord, UK, 33Bardin, L., (1977) Análise de conteúdo, p. 70. , Ediç̃es, LisboaBerkhout, F., Leach, M., Scoones, I., (2003) Negotiating Environmental Changes: New Perspectives From Social Science, , Edward Elgar Publishing Limited, Cheltenham, UKBoholm, A., Editorial: new perspectives on risk communication: uncertainty in a complex society (2008) Journal of Risk Research, 11 (1-2), pp. 1-3Boyne, R., (2003) Risk, , Open University Press, BuckinghamCarvalho, F.M., Chumbo no sangue de crianças e passivo ambiental de uma fundição de chumbo no Brasil (2003) Revista Panamericana de Salud Pública, 1, pp. 19-23(2005) Preventing Lead Poisoning in Young Children, , CDC, US Department of Health and Human Services, CDCCovello, V., Sandman, P.M., Risk Communication: Evolution and Revolution (2001) Solutions to an Environment in Peril, pp. 164-178. , John Hopkins University Press, A.
