At the end of September (28th and 29^th) CERN is organizing two full open days (11hour duration each). This is a really big event (details are getting filled in at http://opendays2013.web.cern.ch/ ), expected to attract 100,000 people!

The experiments are organizing their shows respectively. A number of visitors will go down to the cavern but the vast majority, because of lift limitations, will stay on the surface and visit the various experiments' "tents" and the Globe.

ATLAS- which is at a very central position next to the Globe- is planning to have one or two tents where visitors will go around, get their picture taken, talk to physicists, buy souvenirs, have a kid's corner etc.

"The Discover the COSMOS" and "Go-Lab" projects will be present there and have their own corner where PC's and iPad's will be set-up and have some of projects' labs running for demonstration to the public. The labs include the LHC game and CERNland for smaller kids as well as   HYPATIA,  MINERVA and LHSee for the ATLAS event display and analysis.

The event is organized by the ATLAS outreach group which professor Christina Kourkoumelis is co-coordinating, IASA, EA and EPFL.

A big poster for dissemination purposes will be displayed as well!
