GEC CCP Reactor, Argon Chemistry
This model investigates the National Institute of Standards and Technology (NIST) Gaseous Electronics Conference (GEC) reference cell in two dimensions using the Plasma, Time Periodic interface. A 2D example helps in understanding the physics without excessive CPU time. The cell is ... Mehr lesen
Oxygen Boltzmann Analysis
The Boltzmann equation can be solved to validate sets of electron impact collision cross sections. In fact, sets of collision cross sections are traditionally inferred by solving a two-term approximation to the Boltzmann equation and comparing the results to swarm experiments. This model ...

Electrodeless Lamp
This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... Mehr lesen
Ion Energy Distribution Function in a Capacitively Coupled Plasma Reactor
This model computes the ion energy distribution function (IEDF) for a commercial capacitively coupled plasma reactor. The results show good agreement with experimental data. Mehr lesen
Argon Boltzmann Analysis
The electron energy distribution function (EEDF) plays an important role in the overall behavior of discharges. Analytic forms of the EEDF exist such as Maxwellian or Druyvesteyn, but in some cases they fail to fit the discharge physics. This tutorial model investigates the effects of ... Mehr lesen
Benchmark Model of a Capacitively Coupled Plasma
The underlying physics of a capacitively coupled plasma is rather complicated, even for rather simple geometric configurations and plasma chemistries. This model benchmarks the Capacitively Coupled Plasma physics interface against many different codes. Mehr lesen

Thermoelectric coolers are widely used for electronics cooling in various application areas, ranging from consumer products to spacecraft design. The thermoelectric modules are a common application of thermoelectricity in cooling engineering. They consist of several thermoelectric legs ... Mehr lesen
Double-Headed Streamer in Nitrogen
This tutorial model presents a study of a double-headed streamer in nitrogen at atmospheric pressure. An initial seed of electrons is placed between two electrodes which apply an initial electric field of 52 kV/cm to the gas. A negative and positive streamer propagate toward the ... Mehr lesen
Coil Optimization of an ICP Reactor
This model shows how shape optimization can be used design the coils of an ICP reactor to obtain plasma uniformity. The reactor in study is a planar ICP with the coils distributed along the radial direction. The Optimization study step is used to find the best coil placement so that the ... Mehr lesen
Global Model Coupled with the Two-Term Boltzmann Equation
The electron energy distribution function (EEDF) plays an important role in the overall behavior of discharges. In this example, the formation period of an Argon plasma is studied with special attention paid to the EEDF. The plasma is created within a 4 cm gap by a DC source voltage of 1 ... Mehr lesen
