Abstract

Una pompa getter comprende un involucro a tenuta di gas atto ad essere fissato ad un recipiente sotto vuoto ed una molteplicità di anelli all'interno dell'involucro. Ciascun anello è costituito da un metallo getter non evaporabile poroso sotto forma di particelle sinterizzate e presenta una prima ed una seconda superficie piana tra loro parallele e distanziate di circa 1-10 mm l'una dall'altra, con una superficie piana intermedia tra la prima e la seconda superficie piana ed approssimativamente parallela a queste. Gli anelli sono impilati l'uno sull'altro con la prima superficie piana del secondo anello in contatto con la seconda superficie piana del primo anello e così via e lo spazio compreso tra la superficie piana in-termedia del primo anello e la prima superficie piana del secondo anello costituisce una conduttanza per i gas. Sono inoltre previsti mezzi per riscaldare gli anelli fino alla temperatura di attivazione del getter o di funzionamento.
