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 ...
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.
Plasma-enhanced chemical vapor deposition (PECVD) is a chemical vapor deposition process used to deposit thin films from a gas state (vapor) to a solid state on a substrate. Chemical reactions are involved in the process, which occur after creation of a plasma of the reacting gases. The plasma is generally created by radio frequency (RF ...
Two-stream instability. The two-stream instability is a very common instability in plasma physics. It can be induced by an energetic particle stream injected in a plasma, or setting a current along the plasma so different species ( ions and electrons) can have different drift velocities. The energy from the particles can lead to plasma wave ...
The dimensions on this unit are about 4' x 4' and it weighs more than 300', the maximum thickness it can cut with edge start is 1 1/2" steel. This Wikipedia article has already been disseminated throughout the internet claiming that a hand held plasma can usually cut 2" thick steel, and a automated table system can usually cut 6" thick steel. I ...
Plasma torch. A plasma torch cutter. A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. [1][2][3] The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. [4]
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.
Plasma modeling. Plasma modeling refers to solving equations of motion that describe the state of a plasma. It is generally coupled with Maxwell's equations for electromagnetic fields or Poisson's equation for electrostatic fields. There are several main types of plasma models: single particle, kinetic, fluid, hybrid kinetic/fluid, gyrokinetic ...
