  2. 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 ...

  3. Ultra-high vacuum - Wikipedia

    en.wikipedia.org/wiki/Ultra-high_vacuum

    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.

  4. Getter - Wikipedia

    en.wikipedia.org/wiki/Getter

    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.

  5. Materials for use in vacuum - Wikipedia

    en.wikipedia.org/wiki/Materials_for_use_in_vacuum

    Titanium and niobium are good materials. Solders are sometimes unavoidable for soft-soldered joints. Tin-lead solders (Sn50Pb50, Sn60Pb40, Sn63Pb37) can be conditionally used when the apparatus is not to be baked and operating temperatures aren't elevated (lead tends to outgas).

  6. Titanium - Wikipedia

    en.wikipedia.org/wiki/Titanium

    The processing of titanium metal occurs in four major steps: reduction of titanium ore into "sponge", a porous form; melting of sponge, or sponge plus a master alloy to form an ingot; primary fabrication, where an ingot is converted into general mill products such as billet, bar, plate, sheet, strip, and tube; and secondary fabrication of ...

  7. Heat press - Wikipedia

    en.wikipedia.org/wiki/Heat_press

    A heat press is used to permanently apply a heat transfer to a surface. Common transfer types are Heat Transfer Vinyl cut with a vinyl cutter, Printable Heat Transfer Vinyl, Inkjet Transfer Paper, Laser Transfer Paper, Plastisol Transfers, and Sublimation. Using a Heat Press to apply a heat transfer is a way to ensure accurate time, temperature ...

  8. Ion pump - Wikipedia

    en.wikipedia.org/wiki/Ion_pump

    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 ...

  9. Dye-sublimation printing - Wikipedia

    en.wikipedia.org/wiki/Dye-sublimation_printing

    Dye-sublimation printing (or dye-sub printing) is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate. The sublimation name was first applied because the dye was thought to make the transition between the solid and gas states without going through a liquid stage.
