La SociCti: FranCaise des Ingtnieurs et Techniciens du Vide organise en mai-juin 1972 des Journkes consacrCes $ la

Technologie du vide

et g l’&volution des matCriels et Cquipements de pompage dans le domaine de l’ultra-vide.

Certains des thtmes proposCs aux JournCes de Technologie de 1969 restent encore valables. De nouveaux sujets, tels l’analyse des gaz rCsiduels ou le pompage cryogknique apparaissent comme des techniques nouvelles en plein dCvelop- pement.

Dans cet esprit, les th&mes suivants sont proposCs aux participants:
