Orbitron-ion getter

Orbitron-ion getter pump comprising a flange (1) connected to electrical feedthroughs (13), a with the flange (1) or can be connected, preferably cylindrical pump body (2) and a gas inlet opening (3), one on the flange (1) guided in insulated , in the longitudinal axis direction of the pump body (2) extending, bar-shaped or wire-shaped elongate anode (4) and an electron source (5), emitted by the electron source (5) electrons orbiting the anode (4) with the largest possible free path to in this case to ionize a plurality of being pumped residual gas particles, wherein further a separation of the ionization and the pump chamber by the arrangement of an, in particular cylindrical grating (6), inside which, in particular middle, the at least one anode (4) located, and on the outside a grating (6) surrounding, existing getter material from or coated with this arrangement is provided of the grid (6), dad urch in that the array is an array of elongated blades (7), passing through the grating (6) ions to the disk assembly (7) to be accelerated ...
