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). In the present work, an existing methodology [Sharipov et al., 2006] for the simulation of a Holweck pump with channels of

TMDP technology and modelling challenge (2) May 31, 2011 Confidentiality Label 5 Hybrid or compound turbomolecular pumps were developed from the mid-1980s in which Gaede, Holweck or Siegbahn molecular drag stages were added to the blade stacks to increase compression ratios and to allow the operation of the pumps at higher backing pressures,,. 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.

Siegbahn was a Swedish physicist who won the Nobel Prize for Physics in 1924 for his discoveries and research in the field of X-ray spectroscopy. He was responsible for the development of the Siegbahn Pump.

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.
