GOAL AND OBJECTIVES The ATLAS Visitor Centre welcomes 30,000 visitors each year, providing a view of the ATLAS Control Room and an interactive exhibit on the Experiment and Collaboration GOAL: To enhance the existing facilities with the Globe >ATLAS Path Project, which will accommodate a larger number of visitors, and provide an even more fulfilling experience, especially when it is not possible to visit the underground cavern. OBJECTIVE: This project is to complement the Visitor Centre by providing a focus on the physics of ATLAS through interaction with real detector components in a fascinating and immersive way. It should help visitors to grasp the basic concepts of our detector and how it is used to expand human knowledge of the universe. 3/12/2016 ATLAS Garden Project Team 3

PROJECT DESCRIPTION The Path Project features the development of an outdoor exhibition, integrated into the adjacent landscape connecting CERN’s Globe of Science with the ATLAS Visitor Centre with the following attributes: Create a harmonious connection between the Globe and the ATLAS Visitor Centre Complement the visitor’s experience given by the CERN visit service Offer an independent and complementary method from the “Universe of Particles” exhibition in the Globe centre, including several hands-on exhibits. Multimedia presentations ought to be limited to one or two key areas of the exhibition Use sustainable materials and renewable energy whenever possible. New methods, including those under R&D, can be employed, as this would help to emphasize the role of an experiment for the development of technology Be an open structure that provides adequate protection to the installations from the weather (rain, snow, wind and sun), while allowing the free flow of air. For those parts of the exhibition requiring darkness, special materials will be required to block the light without blocking the air. The structure should be minimally heated during the winter – cool enough to allow visitors leave their coats on, but warm enough for motors and electronics to operate – and provide shade and air flow during the summer. Whenever possible, heating and/or electricity should be provided in an ecological manner (with solar panels, for example). The servers can be hosted remotely in an air- conditioned building; only remote devices and screens will be on site. Be robust and easy to maintain; 3/12/2016 ATLAS Garden Project Team 4

TARGET AUDIENCE 3/12/2016 ATLAS Garden Project Team 5

TARGET AUDIENCE In general, the exhibition will provide two levels of complexity: Those with limited knowledge of particle physics, to whom we must provide basic information to trigger interest in a domain that they might have previously found difficult; Those with previous knowledge of physics and/or physics background, to whom we will need to provide a sufficiently high level of information. That said, the first level of lecture should be highly visual. The second will be provided by a guide for those in guided tours or by support material available in several languages on each area for those touring by themselves. We also foresee exceptional support targeted for specific audiences; in particular for teachers and students who usually prepare their visit in advance 3/12/2016 ATLAS Garden Project Team 6

V ISITS B ACKGROUND Today, all visits to the ATLAS site are organized and groups guided by volunteer physicist; but in the future it is foreseen to become self-exploratory; at least the Path area Groups are of up to 24 people per guide Typical Visit itinerary organized by the CERN visit service includes: a general presentation visit to the Globe of Science ATLAS Visitor Centre 3/12/2016 ATLAS Garden Project Team 7

REQUIREMENTS Complement the visitor’s experience given by the CERN visit service and be coherent whether viewed before the ATLAS Visitor Centre, afterward, or on its own; Generate an element of surprise and wonder among the visitors; Be experimental, interactive and playful; Be intuitive and easy to understand, independent of language or cultural background; Provide support for guides during guided tours, which are the majority of visits to ATLAS today; Provide a second level of information for those visiting by themselves. Provide a clear view of the detector mural located on the nearby wall. 3/12/2016 ATLAS Garden Project Team 8

EXHIBITION CONCEPT We have identified the messages and define the scenario of the exhibition adding suggestions for implementation. However, the supplier will be welcome to propose any new idea that would better achieve our objectives and fulfil our requirements. The concept of the exhibition is to invite visitors to participate in a game, allowing them to cross the detector as particles, interacting with parts of it. Visitors are first presented with a selection of the Big Questions facing mankind in our understanding of the physical universe. They are then introduced to the acceleration process of the particles of the LHC, leading them to the collision. Passing through the “quantum world” the visitors interact with parts of the detector, visualizing the analysis process finally understanding how this process can help physicists to answer some of the Big Questions. 3/12/2016 ATLAS Garden Project Team 9

MOCK UP OF THE INNER DETECTOR We intend to renew the 1:1 mock up of the central part of the detector that might be used in an exhibit at the London Science Museum in the end of 2013; therefore a space on the garden must be foreseen for this piece. The mock up will feature real parts of the detector as well as interactive projection of (live, if possible) event displays. 3/12/2016 ATLAS Garden Project Team 10

ITINERARY Visit duration: 1. Destination ATLAS + The Big Questions (10’) 2. LHC Accelerator (5’) 3. Quantum World (5’) 4. ATLAS Detector (10’) 5. Arrival: New Physics (10’) 3/12/

1-DESTINATION: ATLAS Main Message: You are entering the ATLAS detector site. ATLAS is a particle detector at one of the four collision points of the LHC. It is designed to analyse particles produced by the collisions, providing us with a glimpse of the very early universe. Supplementary Messages: It is one of the largest and most precise scientific instruments ever constructed. Size and precision are necessary to discover new phenomena produced in the high energy collisions of the LHC. ATLAS physicists are trying to answer some of the Big Questions about the origin, composition, and fate of our universe 3/12/2016 ATLAS Garden Project Team 13

2 – LHC ACCELERATOR Main Message: The LHC accelerates protons to high energies colliding them at the very centre of ATLAS and the other detectors simultaneously. High energy is required to produce particles of high mass (E = mc^2). Supplementary Messages: Accelerating particles gives them energy. The energy produced at the LHC has never been achieved before; that is why we hope to find new particles not yet observed. Implementation suggestion: Create a Zoetrope installation, which provides the sensation of being accelerated by the LHC. It should include a device to build acceleration and trigger collisions. Projection of collisions when sufficient energy is achieved and beams are lined up. Inspiration: 3/12/2016 ATLAS Garden Project Team 14

3- QUANTUM WORLD Main Message: We know what goes into a collision and we can measure what comes out, but what happens in between is ruled by chance. Although we never see what happens in this "Quantum World", we study it by detecting the particles that come out of it. Supplementary Messages: Any one of an infinite number of paths could be taken, some more frequently than others. Implementation suggestion: Projection or mirror game with visitor’s image transformed. Visitors come in and see their reflection transforming into waves; parts of these reflections spread through out the space. The waves must transform back into several particles, different than the original visitor. Inspiration: 3/12/2016 ATLAS Garden Project Team 15

4 – THE ATLAS DETECTOR Main Message: ATLAS is made up of specialized sub-detectors, each designed to measure the various types of particles that emerge from the collision. Supplementary Messages: Different particles leave different traces in different parts of the detector. ATLAS measures the characteristics of particles such as: direction, momentum and energy. Show examples of how we detect and measure: electrons, photons, protons, neutrons and muons. Implementation suggestion: Use the ATLAS mock up as portal including real parts of the detector. Invite the visitor to follow the path of one of these particles through ATLAS: Dark atmosphere with big interactive floor that displays the trajectories of the particles as the visitors passes through the 4 ATLAS subsystems. The projection of the traces could be reflected in the wall. To complement the explanation, there should be 4 stands with real pieces of the detector and more information about them /12/2016 ATLAS Garden Project Team 16

5- ARRIVAL:NEW PHYSICS Main Message For each collision, scientists combine the particles in order to understand what happen during the collision. This is called reconstruction of the event. We have to reconstruct trillions to find few events that are new and interesting. The more of these events you find the more accurate your measurements. Supplementary Messages: One must analyse a lot of data to search for new and rare phenomena. Science advances in a cycle: questions > theories > measurements > new questions and answers > new theories 3/12/2016 ATLAS Garden Project Team 17

NOTES 1. Renew of the ATLAS visitor centre - Although we don’t foresee a dramatic change in the layout of the ATLAS Visitor Centre, we must make sure that it complements the content that the path will offer. Central to the layout of the Visitor Centre is a view of the ATLAS control room. It is thus natural for the content to focus on the collaboration and its role in the construction and running of the experiment. This includes detector hardware, trigger, computing and physics analysis. 1. It must also take into consideration the proposed landscaping project of Charles Jenks and Group H around the Globe, which might include the construction of a reception building. 2. It shall also allow the participation of research institutes or universities related to ATLAS that are developing innovative technologies in renewable energy. 3. The servers can be hosted remotely in an air- conditioned building; only remote devices and screens will be on site. 4. We also foresee exceptional support targeted for specific audiences; in particular for teachers and students who usually prepare their visit in advance 3/12/2016 ATLAS Garden Project Team 21
