Principle of sputtering ion pump and titanium pump

As early as the beginning of this century, some people in the metal vacuum electron tube evaporation of some chemical activity and strong, so that it failed to and tube net pumping gas reaction, thereby reducing the gas molecule concentration space.( Titanium Casting Manufacturer )

  This metal and plays the same role is called a getter material, this method is called the chemical cleaning. Experiments show that, using titanium continuous evaporation to a cooling wall, can be formed with considerable pumping speed of the titanium pumps , the formation of simple sublimation pump.
