Getter pumping system particularly useful for linear accelerators or more generally high-volume environments, wherein a plurality of getter cartridges (100, 100, 100, . . . 100.sup.n) having a linear support (110, 110, 110, . . . 110.sup.n) and a plurality of linear heaters (120, 120, . . . 120.sup.n) are connected in a high-density configuration to a wall (11) that has a surface area of at least 0.5 m.sup.2.

Provided is an ultra-high vacuum forming device containing an ion pump having a compact size in the central axis direction. The ultra-high vacuum forming device (1) is provided with at least one ion pump (100). The ion pump (100) is provided with: a casing (110) having at least one opening (111, 112); a board-shaped electrode group (120) formed by means of a central opening (120a) being formed along a predetermined central axis (C) disposed within the casing (110), and a plurality of electrodes (121) being joined with spaces therebetween; a pair of board-shaped electrodes (131, 132) having a different polarity than that of the electrode group (120) and that are disposed at positions sandwiching both sides of the electrode group (120) within the casing (110); and a pair of board-shaped magnets (141, 142) disposed at positions sandwiching both sides of the pair of board-shaped electrodes (131, 132).

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.
