A titanium sublimation pump (TSP) is a type of vacuum pump used to remove residual gas in ultra-high vacuum systems, maintaining the vacuum. Principle of operation
Ion pumps; Titanium sublimation pumps; Non-evaporable getter (NEG) pumps; Cryopumps; Diffusion pumps, especially when used with a cryogenic trap designed to minimize backstreaming of pump oil into the systems. Turbo pumps and diffusion pumps rely on supersonic attack upon system molecules by the blades and high speed vapor stream, respectively.
Getter pump or sorption pump In laboratory vacuum systems, the bulk NEG getter is often held in a separate vessel with its own heater, attached to the vacuum system by a valve, so that it can be replaced or renewed when saturated. [8] Ion getter pump Uses a high voltage electrode to ionize the gas molecules and drive them into the getter surface.
Tungsten disulfide used to be significantly more expensive, but molybdenum disulfide prices have risen to a comparable range. [7] Usable from −188 to +1316 °C in vacuum, from −273 to +650 °C in normal atmosphere. [8] Hexagonal boron nitride is a graphite-like dry lubricant used in space vehicles. Ernest Lawrence's 4-inch cyclotron. A D ...
A sublimatory [1] [2] or sublimation apparatus is equipment, commonly laboratory glassware, for purification of compounds by selective sublimation. In principle, the operation resembles purification by distillation , except that the products do not pass through a liquid phase .
Titanium alloys are used in spectacle frames that are rather expensive but highly durable, long lasting, light weight, and cause no skin allergies. Titanium is a common material for backpacking cookware and eating utensils.
A noble diode pump is a type of ion pump used in high-vacuum applications that employs both a chemically reactive cathode, such as titanium, and an additional cathode composed of tantalum. The tantalum cathode serves as a high-inertia crystal lattice structure for the reflection and burial of neutrals, increasing pumping effectiveness of inert ...
