Manne Siegbahn was married and he and his wife Karin had two sons. The elder son, Bo, became a member of parliament and ambassador, and the younger, Kai, became a physicist like his father and received the Nobel Prize of physics in 1981. Manne Siegbahn died in 1978 at and age of 92 years. Back to Research activities.

Siegbahn's precision measurements drove many developments in quantum theory and atomic physics. Awards and honours. Siegbahn was awarded the Nobel Prize in Physics in 1924. He won the Hughes Medal 1934 and Rumford Medal 1940. In 1944, he patented the Siegbahn pump. Siegbahn was elected a Foreign Member of the Royal Society in 1954. Personal life

The present invention provides a vacuum pump ( 10 ) which comprises a turbo-molecular pumping mechanism ( 12 ) in series with a Siegbahn pumping mechanism ( 14 ). A first pump inlet ( 16 ) is provided through which gas can pass through both the turbo-molecular pumping mechanism and the Siegbahn pumping mechanism.

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 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. Holweck TMDP design (courtesy of Pfeiffer Vacuum), with stages in series nested radially TwisTorr(Siegbhan pump redesigned) is Agilent molecular drag TMDP design on new products (from 2010), with stages axially in series.
