- In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC study covered an energy-frontier hadron collider (FCC-hh), a highest-luminosity high-energy lepton collider (FCC-ee), the corresponding 100km tunnel infrastructure, as well as the physics opportunities of these two colliders, and a high-energy LHC, based on FCC-hh technology. This document constitutes the third volume of the FCC Conceptual Design Report, devoted to the hadron collider FCC-hh. It summarizes the FCC-hh physics discovery opportunities, presents the FCC-hh accelerator design, performance reach, and staged operation plan, discusses the underlying technologies, the civil engineering and technical infrastructure, and also sketches a possible implementation. Combining ingredients from the Large Hadron Collider (LHC), the high-luminosity LHC upgrade and adding novel technologies and approaches, the FCC-hh design aims at significantly extending the energy frontier to 100TeV. Its unprecedented centre of-mass collision energy will make the FCC-hh a unique instrument to explore physics beyond the Standard Model, offering great direct sensitivity to new physics and discoveries.

- We review the physics opportunities of the Future Circular Collider, covering its e+e-, pp, ep and heavy ion programmes. We describe the measurement capabilities of each FCC component, addressing the study of electroweak, Higgs and strong interactions, the top quark and flavour, as well as phenomena beyond the Standard Model. We highlight the synergy and complementarity of the different colliders, which will contribute to a uniquely coherent and ambitious research programme, providing an unmatchable combination of precision and sensitivity to new physics. © 2019, The Author(s).

Forensic virtual reality : Investigating individual behavior in the MGM Grand fire

- The forensic investigation of human behavior in fires can benefit from a first-hand perspective of what happened during the fire. Complementing the on-site investigation and the witnesses’ accounts with a virtual reality replication of the real fire, forensic investigators could gather valuable data from having non-victims experiencing it. This paper aims to introduce and develop the forensic virtual reality method as a tool to provide a better understanding of the behavior of the building occupants. To assess the method, a virtual reality scenario based on the conditions in a hotel room during the MGM Grand fire in 1980 was created, and 55 naïve participants were exposed to it. Their behavior was later compared to that of the survivors of the real fire. The results show that the virtual environment made approximately 50% of the participants feel urgency due to the emergency and act on it. A comparison to the data from the MGM Grand fire confirmed that real life behavior can be observed in the virtual environment, although the frequencies of actions performed were lower in the virtual reality experiments.

- Evacuation times can be shortened in fire scenarios if people choose appropriate routes. Way-finding systems can be used to aid this process, thus their effectiveness needs to be evaluated. In the present study, the way-finding evacuation systems of the Future Circular Collider (FCC) of the European Organization for Nuclear Research (CERN) are investigated as its evacuation design presents several challenges from the fire safety perspective. To perform a comparison of different evacuation design solutions, a set of Virtual Reality (VR) experiments involving a total of 111 participants was performed. VR was used because the FCC facility is not built yet, and it allows for high experimental control and cost-effectiveness for comparisons of way-finding systems. The VR experiments reproduced a hypothetical fire emergency in which participants’ egress behaviour was investigated. Three scenarios were represented, each of them adopting different evacuation safety concepts and way-finding systems. Different installations were included in the scenarios, such as scenario (1) flashing lights, scenario (2) static or dynamic signage (i.e. active and dissuasive signage indicating the direction towards or away from the danger) and scenario (3) a robot placed on a monorail on the vault of the tunnel, able to localize people in the tunnel and provide way-guidance information. Results show that the combination of red flashing lights at the exits, dynamic signage and a robot equipped with green flashing lights yielded the highest compliance to the way-finding intent of the system (92.6% compliance vs 62.9% and 77.5% for scenarios 1 and 2 respectively).

A fire safety assessment approach for evacuation analysis in underground physics research facilities

- This paper introduces an integrated approach for evacuation assessment of nuclear physics research facilities exposed to fire risk. The approach combines the use of a simplified egress modelling method and advanced agent-based simulations of evacuation. An integrated multi-model approach is proposed here given the varying level of complexity concerning evacuation safety in underground physics facilities. This paper introduces a simplified probabilistic egress model based on existing hand calculations for 1D smoke spread modelling and it suggests a procedure for its combined use with advanced agent-based evacuation simulations. This includes the use of the outputs of the simplified egress model in underground smoke-filled portions of underground nuclear research facilities (e.g. tunnel arcs) as an input for complex agent-based evacuation simulations in the underground access shafts. An exemplary application of the integrated approach is presented for the simulation of a set of hypothetical fire risk scenarios in the Future Circular Collider (FCC) at CERN. This approach is deemed to facilitate fire evacuation safety assessment in underground physics research facilities by optimizing the simulation of relevant fire risk scenarios. A discussion on the advantages and implications of the use of an integrated approach in comparison with other safety assessment methods is presented.
