ABSTRACT:
A bulk getter-pump, consisting primarily of large beds of heated getter-material for use in pumping down in a high-vacuum environment. The pump is designed for applications now are served by turbo, cryo, diffusion, and ion pumps. The pump consists of a meshed cage filled with bulk getter-material pellets, which cage is housed in a housing coupled to a conduit of a vacuum chamber, so that the bulk getter-material is exposed to the interior of the vacuum chamber. In use, a roughing pump is first used to bring the chamber down to a pressure of about 10.sup.3 torr, and then the bulk getter-pump of the invention is operatively coupled to the chamber for sorbing gases, in order to reach a high vacuum.
