  2. Plasma cutting - Wikipedia

    en.wikipedia.org/wiki/Plasma_cutting

    Plasma cutting. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops ...

  3. Pinch (plasma physics) - Wikipedia

    en.wikipedia.org/wiki/Pinch_(plasma_physics)

    Basic mechanism. This is a basic explanation of how a pinch works. (1) Pinches apply a high voltage and current across a tube. This tube is filled with a gas, typically a fusion fuel such as deuterium. If the product of the voltage & the charge is higher than the ionization energy of the gas the gas ionizes. (2) Current jumps across this gap.

  4. Plasma etching - Wikipedia

    en.wikipedia.org/wiki/Plasma_etching

    A plasma etcher, or etching tool, is a tool used in the production of semiconductor devices. A plasma etcher produces a plasma from a process gas, typically oxygen or a fluorine -bearing gas, using a high frequency electric field, typically 13.56 MHz. A silicon wafer is placed in the plasma etcher, and the air is evacuated from the process ...

  5. Computer-aided manufacturing - Wikipedia

    en.wikipedia.org/wiki/Computer-aided_manufacturing

    Computer-aided manufacturing. CAD model and CNC machined part. Computer-aided manufacturing (CAM) also known as computer-aided modeling or computer-aided machining[1][2][3] is the use of software to control machine tools in the manufacturing of work pieces. [4][5][6][7][8] This is not the only definition for CAM, but it is the most common. [4]

  6. ARC fusion reactor - Wikipedia

    en.wikipedia.org/wiki/ARC_fusion_reactor

    ARC fusion reactor. The ARC fusion reactor (affordable, robust, compact) is a design for a compact fusion reactor developed by the Massachusetts Institute of Technology (MIT) Plasma Science and Fusion Center (PSFC). ARC aims to achieve an engineering breakeven of three (to produce three times the electricity required to operate the machine).

  7. Computer-generated imagery - Wikipedia

    en.wikipedia.org/wiki/Computer-generated_imagery

    Volume rendering. v. t. e. Computer-generated imagery (CGI) is a specific-technology or application of computer graphics for creating or improving images in art, printed media, simulators, videos and video games. These images are either static (i.e. still images) or dynamic (i.e. moving images). CGI both refers to 2D computer graphics and (more ...

  8. Plasma parameters - Wikipedia

    en.wikipedia.org/wiki/Plasma_parameters

    Fundamental. [] The fundamental plasma parameters in a steady state are. the number density of each particle species s present in the plasma, the temperature of each species, the mass of each species, the charge of each species, and the magnetic flux density B . Using these parameters and physical constants, other plasma parameters can be derived.

  9. Plasma (physics) - Wikipedia

    en.wikipedia.org/wiki/Plasma_(physics)

    The plasma approximation: The plasma approximation applies when the plasma parameter Λ, [26] representing the number of charge carriers within the Debye sphere is much higher than unity. [ 19 ] [ 20 ] It can be readily shown that this criterion is equivalent to smallness of the ratio of the plasma electrostatic and thermal energy densities.
