The EDUSAFE project EDUSAFE is a 4-year Marie Curie ITN project, funded by FP7, which focuses on research into the use of Virtual Reality (VR) and Augmented Reality (AR) during planned and emergency maintenance in extreme environments (nuclear installations, space, deep sea etc.) such as the ATLAS cavern at CERN. Goal: technically advance and combine several technologies and integrate them to form a Mobile Personnel Safety System (PSS) improving safety and radioprotection, reducing errors and decreasing the time needed for scheduled or sudden interventions. Results: Augmented Reality glasses + smart helmet allowing bidirectional communication with the EDUSAFE Supervision System used for guidance and radioprotection purposes. 2nd example Mobile Personnel Safety System / AR glasses Electronics, mechanics, physics, radiation calcs, fast wireless transmission, computer vision.. 1st example Radiation Hot Spot Localization /iPad View 03.06.2016 HNPS 2016

NTUA ESR 5 - Control System (CS) and Data Acquisition System (DAQ) architecture The CS and DAQ System is based on the ATLAS Personnel Visualizer System (APVS) part of the ATLAS Wireless Safety System (AWSS) that has been developed during the CERN’s WPSS project. DAQ Server (sensor data in JSON formatted messages). GWT application responsible for the GUI (EDUSS) for real-time supervision monitoring (iPad, desktops). The Software Architecture design of the Control System and Data Acquisition System of EDUSAFE is graphically shown in Figure 1. This system is consisted of the following SW functional blocks: Java Server. This SW is developed in Java programming language and is responsible for developing the web application that is needed in order to communicate with the client-side. EDUSAFE User Interface running on the browser client is developed through web-based methods to enable the supervision of the personel in the ATLAS environment. DAQ Server. This SW is also developed in Java and enables the acquisition of the various sensor data. Oracle Database SW is used to store data for various purposes such as offline analysis. 03.06.2016 HNPS 2016

DAQ HW sources The DAQ System can wirelessly acquire various types of data from all the subsystems: 1) The Mobile Personal Supervision System (MPSS), video/audio/radiation data. 2) The sensor board, environmental and biological parameters (JSON messages). For example: Temperature, Barometric Pressure, Humidity, O2, Fall Detection. 03.06.2016 HNPS 2016

DAQ HW sources 3) The gamma camera, radiation hot spot localization images. 4)The dosimeter used for the radiation measurements. In case a measurement exceeds a certain threshold the CS creates alarm notifications. Once the data are acquired they are shown on the developed EDUSS GUI and stored in an Oracle Database for off-line analysis. Edupix gamma camera using Timepix chip, a single-pixel read-out chip. The system allows operators to visualize the locations of the main surrounding radioactive sources that contribute to their current dose rate directly on the EDUSAFE prototype display, so that they may perform their work accordingly, respecting ALARA (As Low As Reasonably Achievable) principles for minimizing occupational exposure. 03.06.2016 HNPS 2016

EDUSAFE Supervision System User Interface The EDUSS GUI is developed in order to monitor the various worker sessions and guide the personnel if needed in the ATLAS cavern. Through the EDUSS GUI the supervisor can: Create multiple sessions with the workers in the ATLAS cavern. Monitor each worker (real-time video streaming and audio). Monitor the sensor values and the gamma radiation measurements corresponding to the dosimeter of each specific worker. Generate and save plots of the complete session for each sensor type resulting in faster offline analysis of the acquired data (Highcharts SW). 03.06.2016 HNPS 2016
