3. Vacuum pump - Wikipedia

   en.wikipedia.org/wiki/Vacuum_pump

   The Roots blower is one example of a vacuum pump. A vacuum pump is a type of pump device that draws gas particles from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity. [1]

   Vacuum systems usually consist of gauges, vapor jet and pumps, vapor traps and valves along with other extensional piping. A vessel that is operating under vacuum system may be any of these types such as processing tank, steam simulator, particle accelerator, or any other type of space that has an enclosed chamber to maintain the system in less than atmospheric gas pressure.

7. Titanium sublimation pump - Wikipedia

   en.wikipedia.org/wiki/Titanium_sublimation_pump

   Samples may become contaminated by titanium if they have line-of-sight to the pump. Also, titanium is a very hard material, so titanium film which builds up on the inside of the chamber may form flakes which fall into mechanical components (typically turbomolecular pumps and valves) and damage them. Many chambers containing TSPs also have an ...
