CERN Open Days 2013 27th, 28th & 29th of September Vacuum Surfaces & Coating

Friday 27th of September: visit for the VIPs Saturday 28th and Sunday 29th of September: visit for the general public SMA18: Le vide, un monde rempli d’idées. Les visiteurs découvriront les étonnantes propriétés du vide au travers d’un parcours ludique. Il vous sera montré que sous vide, les objets se déforment, que le son devient inaudible, que les plumes tombent aussi vite que le plomb, et bien d’autres choses. Les plasmas de gaz raréfiés seront aussi dévoilés, ainsi que leurs applications dans la production de revêtements bien plus fins qu’un cheveu.  La caisse à outils des experts sera ouverte : matériaux, pompes et instruments de mesure vous seront accessibles.    113: Le vide et le LHC. Dix mille milliards de fois moins dense : c'est l’atmosphère dans laquelle les particules des faisceaux circulent dans le LHC. Pour y parvenir, matériaux, traitements thermiques et de surfaces internes des chambres à vide, étanchéité  sont choisis avec des critères très rigoureux. Il vous sera proposé de découvrir les secrets de la technologie de l’ultravide et parcourir les difficultés qu'il convient de surmonter afin de créer et préserver la faible densité de matière: une petite portion d’espace interstellaire sous vos pieds et devant vous !     

Building SMA18 “Vacuum is a world full of ideas” 14 activities 13 animators 2 flow regulators

Building 113 “Vacuum and the LHC” 5 activities 5 guides 1 flow regulator

Each guide or animator will receive the technical sheets of the activities. On them you will find: - how to operate the activity - the scientific explanation - some additional information to better answer questions from the public An A0 poster describing the activity will be installed next to each one Friday 20th of September at 9:00 am: Training of the volunteers on the experiments
