Sputtering ion pump
Web6 Oct 2024 · Sputtering is the knocking off of substrate atoms by an incident energetic particle. In pressure regimes where ion pumps are useful, the mean free path of a gas atom/molecule is much larger than the size of the system- this is often called ballistic transport since the molecule bounces off walls way more than hitting other gas molecules. WebGamma Vacuum designs, manufactures, and services ion pumps, titanium sublimation pumps, and their controls. We have grown to be an industry leading ion pump supplier …

In particular, an innovative alloy as a thin … The first evidence for pumping from electrical discharge was found 1858 by Julius Plücker, who did early experiments on electrical discharge in vacuum tubes. In 1937, Frans Michel Penning observed some evidence of pumping in the operation of his cold cathode gauge. These early effects were comparatively slow … See more The basic element of the common ion pump is a Penning trap. A swirling cloud of electrons produced by an electric discharge is … See more Ion pumps are commonly used in ultra-high vacuum (UHV) systems, as they can attain ultimate pressures less than 10−11 mbar. In contrast to … See more There are three main types of ion pumps: the conventional or standard diode pump, the noble diode pump and the triode pump.
