| 释义 |
A Holweck pump is a type of vacuum pump that utilises the drag of air molecules against a rotating surface.[1] The modern turbomolecular pump is a more advanced version based on similar operation, and a Holweck pump is often used as the backing pump for it. The Holweck pump can produce a vacuum as low as {{convert|1e-8|mmHg|Pa|abbr=on}}. InventionThe device was invented in the early 1920s by Fernand Holweck as part of his apparatus for his work in studying soft X-rays. ManufactureIt was manufactured by French scientific instrument maker, Charles Beaudouin.[2] References1. ^{{cite journal|last1=Naris|first1=Steryios|last2=Koutandou|first2=Eirini|last3=Valougeorgis|first3=Dimitris|title=Design and optimization of a Holweck pump via linear kinetic theory|journal=Journal of Physics: Conference Series|volume=362|year=2012|pages=012024|issn=1742-6596|doi=10.1088/1742-6596/362/1/012024}} 2. ^D.
