TMDP technology and modelling challenge (2) May 31, 2011 Confidentiality Label 5 The Siegbahn type molecular pump is the vacuum pump in which the rotary disk gives a momentum in a direction tangential to the rotary disk (i.e., direction tangential to the rotating direction of the rotary disk) to gas molecules that have dispersedly entered the spiral groove flow paths. Siegbahn was awarded the Nobel Prize in Physics in 1924. He won the Hughes Medal 1934 and Rumford Medal 1940.

One issue was pumping speed: alternatives such as the diffusion pump are much faster. Siegbahn was later to describe a hybrid Siegbhan-Gaede mechanism of speed 48 l/s. A large pump (disc diameter 540mm) was built for the cyclotron at the Nobel Institute which had 3 spiral grooves (in parallel) and a pumping speed of 73 l/s.

The “T” or “Triplex” variant contains turbomolecular blades, a Siegbahn drag mechanism and a regenerative mechanism. The Holweck pump belongs to the category of drag pumps which also includes between others the Gaede and the Siegbahn pumps.

[1]Personer med efternamnet Siegbahn. Bo Siegbahn (1915–2008), ambassadör, politiker och författare The Holweck pump is a device widely used in many pumping systems. It can be a self-standing device or part of a multi-stage system, usuallycombined with a turbo-molecular pump (TMP).

change depending on the behavior of a vane-type vacuum pump. Siegbahn pump by CFD methodology, International Journal of Vacuum, vol.53, no.1, 

Siegbahn was later to describe a hybrid Siegbhan-Gaede mechanism of speed 48 l/s. A large pump (disc diameter 540mm) was built for the cyclotron at the Nobel Institute which had 3 spiral grooves (in parallel) and a pumping speed of 73 l/s. The computational fluid dynamics (CFD) methodology is successfully applied to investigate the flow field of the Siegbahn vacuum pump. The rotor is equipped with 18 helical grooves that are separated by thin blades on both the upper and lower planes. Of vacuum pumps, a Siegbahn type molecular pump with a Siegbahn type configuration has rotating discs (rotating circular plates) and stator discs arranged with a gap (clearance) with the rotating Siegbahn stages modeling concepts •Siegbahn stages are mainly characterized by a flow • in the direction tangential to the spiral channel (rotation of the disk) • in the direction normal to the channel (pressure gradients) •In general, the same considerations made for the Holweck pump could be According to a preferred embodiment of the invention, the rotor and / or the stator are designed as a Holweck pumping stage and / or Siegbahn pumping stage and / or as a cross-channel pumping stage Drag pumps --1912 W.Gaede --1922 F.Holweck -1929 M.Siegbahn 1958: First Turbo Molecular pumps : -Double-Ended design (Becker) Axial flow principle (Hablanian).
