ABSTRACT:
A getter sorption pump has at least one getter member of non-evaporation getter material and a corresponding heating element. With this getter pump, a high pump rate is achieved by means of an extremely large surface in the smallest possible space. For this purpose, the heating element is disposed in an insulating tube and a plurality of individual getter members are attached to the insulator tube at a spacing from one another. The getter pump is employed in high-vacuum and gas discharge systems.
