Siegbahn pump

Manne Siegbahn was a Swedish physicist, who won the Nobel Prize in Physics in 1924. Check out this biography to know about his childhood, life, achievements, works & timeline. 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. Additionally, an inter-stage (inlet18) is provided through which gas can enter the pump … The present invention provides a vacuum pump ( 10 ) which comprises a turbo-molecular pumping mechanism ( 12 ) in series with a Siegbahn pumping mechanism ( 14 ).

Fig. 3 Siegbahn pump In spite of its attractive properties the molecular pump, irrespective of its construction, has not been appliied much. The good properties are: The high vacuum free from vaposrs, the fast readiness for operabi'on, no sensitivity against at- mospheric pressure.

Holweck pumps have been frequently modeled theoretically. Siegbahn. Another design was given by Manne Siegbahn. He had produced a pump which was used in 1926. About 50 of Siegbahn's pumps were made from 1926 to 1940. In 1943, Seigbahn published a paper regarding these pumps, which were based on a rotating disk.

1938 – 1947 President, International Union of Pure and Applied Physics. 1939 Member, International Bureau of Weights and Measures. 1940 Awarded the Rumford Medal, Royal Society.
