Bruno Lenski will give you a general overview of CERN and will reply to your questions from 14:00 to 14:50 in room 513-R-070. He will then accompany you to the AD factory in building 193: you will be split into two groups there for safety reasons: the two guides will be François Butin and Bruno Lenski. The AD visit will start at 15:00 and end at 15:50.
