The Institute of Accelerating Systems and Applications (IASA) was founded in 1994 in order to promote research and postgraduate studies in the Greek University system. It is affiliated with six university departments: Medicine, Physics and Informatics of the University of Athens and Electrical & Computer Engineering, Chemical Engineering and General Science of the National Technical University of Athens. IASA also has a number of support divisions, ranging from computing and electronics to medical physics, which support and enhance the capabilities of the individual research areas.The IASA outreach team has been a member of the ATLAS experiment at the LHC for more than 15 years and has played a central role in its outreach group. The general goal of its activities is to provide simple and user-friendly interactive interfaces to simulate the procedures used by high-energy physics researchers. To this end, the IASA group has authored the ATLAS interactive event analysis tool HYPATIA (HYbrid Pupil’s Analysis Tool for Interactions in ATLAS) which has won the 2016 Global Online Laboratory Consortium award for the best “Visualized experiment” which allows high school students to analyse real data from the LHC.
