Applications

GEC reference cell Screenshot of GEC ref cell model The Gaseous Electronics Conference (GEC) reactor has been designed to serve as a reference for experimental and modeling studies. PLASIMO results are compared to experimental data for a capacitively coupled argon plasma.

Sputtering hollow cathode discharges Screenshot of HCD model PLASIMO has been used to facilitate in-depth studies of sputtering hollow cathode discharges (HCD). The constructed models have been validated by comparison with experimental data, and have been used to optimize the operating conditions and the HCD geometry for effcient laser oscillation. Furthermore, PLASIMO has been used to design a novel hollow cathode construction.

Mercury-free high intensity discharge lamp Picture of calculated spectrum In mercury-free lamps, the dominant mercury background gas is replaced with salts like InI and SnI. Modeling of such a complex chemistry becomes very challenging. The PLASIMO radiation energy transport (raytracing) module has been used to simulate the complete spectra of such lamps.

DC glow discharge tube Screenshot of glow discharge model The PLASIMO time-dependent Drift-Diffusion model is used for simulation of a DC glow discharge tube. The model accurately captures the structure of the discharge: cathode fall region, negative glow, Faraday dark space and positive column.

Plasma needle Pcture of plasma needle The plasma needle is a small (~ 1 mm) atmospheric, non-thermal, radiofrequency plasma, generated at the tip of a metal wire. The PLASIMO time-dependent Drift-Diffusion model is used to describe the plasma properties and to provide insights into the physical processes.

Global modeling of complex mixtures The PLASIMO Global Model has been used to model very complex mixtures, such as CO2, H2O-He, H2-N2-O2, H2-N2-O2-C and O2-SiCl4. Many other mixtures are available in the PLASIMO database.

Cascaded arc Screenshot of cascaded arc model PLASIMO has been used for simulating a plasma source for material research under fusion-relevant conditions (Magnum-PSI). PLASIMO succesfully handles the challenging combination of the transonic flow field and the magnetic confinement.

Coaxial waveguide Picture of coaxial waveguide PLASIMO has been used to study a coaxial configuration. The plasma is formed around a quartz tube and acts as an outer conductor in such a way that a spatially extended surface wave is created.

Surfatron plasma source PLASIMO has been used in a number of surfatron plasma studies. For the first time, it permits describing self-consistently the plasma inside and outside the surfatron cavity.

COST reference jet Picture of COST jet model The PLASIMO Drift-Diffusion module coupled with the flow module is used for self-consistently modeling the plasma behavior in jets.

Plasma shower Picture of plasma shower - velocity vector The plasma shower is an atmospheric pressure high density rf plasma developed for material processing. PLASIMO has been used to describe the plasma behavior and to facilitate in-depth studies of the various aspects of the plasma shower.

Microwave plasma deposition source PLASIMO has helped in designing and optimizing a microwave reactor for depostion of SiO2 for optical fiber production. The modeling studies demonstrated that the reactor geometry can be altered to confine the plasma and thus to achieve more uniform and controlled deposition profile.

Streamers Picture of a streamer PLASIMO can be used for simulations of streamers and streamer-like discharges. A model for a positive streamer in air has been validated by comparison with other simulation codes. Results are published in "Comparison of six simulation codes for positive streamers in air", B.Bagheri etal., Plasma Sources Science and Technology, 27:095002. Read article
