ABSTRACT:
A getter pump with high gas sorption velocity includes a cylindrical housing that has an open end and a closed end and defines a chamber with a central axis. Three to eight getter structures are disposed within the chamber. The getter structures are symmetrically arranged around the central axis of the chamber and are substantially parallel to the central axis of the chamber. Each of the getter structures includes a plurality of porous disks of getter material disposed on a central shaft. A heater is centrally disposed within the chamber such that the heater is substantially coaxial with the central axis of the chamber.
