Abstract
A getter pump is described. The getter pump has a casing, whose shape is a solid of revolution with a revolution axis, and a plurality of getter cartridges mounted within the getter pump casing, each cartridge having a linear central support and spaced getter elements mounted on the linear central support. A getter cartridge orientation plane containing the linear central support and parallel to the revolution axis and a getter cartridge positioning plane orthogonal to the revolution axis and intersecting the midpoint of a linear central support are defined. For each cartridge, the angle formed by the getter cartridge positioning plane with the linear control supports is equal to or less than 30°.

A getter pump comprising:
- a casing, whose shape is a solid of revolution with a revolution axis, and
- a plurality of getter cartridges mounted within said getter pump casing, each cartridge comprising a linear central support and spaced getter elements mounted on said linear central support,
- wherein, for each getter cartridge:
- a getter cartridge orientation plane containing the linear central support and parallel to the revolution axis is defined,
- a getter cartridge positioning plane orthogonal to the revolution axis and intersecting the midpoint of the linear central support is defined, and
- the angle formed by said getter cartridge positioning plane with the linear central support is equal to or less than 30°, preferably equal to or less than 10°.
