The additional Siegbahn pump stage can be realized with a relatively small effort and in a small construction space and it has been found that the additional pump action provided by the Siegbahn pump stage is suitable to compensate a reduction in the suction power of the pump due to gas friction in the intermediate space between the motor stator and the rotor so that a compact and high
Siegbahnsparken, döpt efter nobelpristagarna Kai och Manne Siegbahn, invigs den 26 oktober. Förutom en ekologisk funktion innehåller parken en ambitiös lekplats i flera delar och flera konstverk av konstnären Mattias Bäcklin. Förutom ansvariga politiker så gästas invigningen av Hans Siegbahn, son och sonson till de fysiker som parken fått namn efter.

It can be a self-standing device or part of a multi-stage system, usuallycombined with a turbo-molecular pump (TMP). In the present work, an existing methodology [Sharipov et al., 2006] for the simulation of a Holweck pump with channels of
The turbomolecular pump as first described in 1958 by Becker, was based on the older molecular drag pumps developed by Gaede in 1913, Holweck in 1923 and Siegbahn in 1944.
