Han var son till stationsinspektor Georg Siegbahn och Emma Zetterberg. [4] Han avlade studentexamen i Stockholm 1906 och började studera på Fysiska institutionen vid Lunds universitet samma år. [5] Elektronmikroskop enligt Siegbahn-Schönander. Spänning 30-85 kV. Förstoring 30.000 X. 1) Strålningsenhet med manöverpulpet. Gul, horisontell, på järnprisma, liggande på skåp (grått), av pulpetmodell, med manöverdon och utrymme för vacuumaggregat. The present invention provides a vacuum pump ( 10 ) which comprises a turbo-molecular pumping mechanism ( 12 ) in series with a Siegbahn pumping mechanism ( 14 ).

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. Turbomolecular pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface. The “D” or “Duplex” variant contains turbomolecular blades and a Siegbahn drag mechanism allowing operation at higher backing pressures than pure turbomolecular pumps. 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. It is composed by an inner rotating cylinder (rotor) and an outerstationarycylinder (stator).
