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°.
