Operation • Electrodeless inductive coupling allows use with chemically reactive gases • Low power (300 mW 3 W), low voltage (< 20 V) • Gas pressure: 0.1 10 Torr (13 1300 Pa) • Argon ion density: 1010 1011 cm-3 • Electron temperature: 20,000 50,000 K • Non-equilibrium plasma allows operation near room temperature, however. MEMS Plasma Generator A low power, electrodeless plasma source on a chip...

In typical conditions of diamond film synthesis in a EACVD device ~JllectronAssisted Chemical Vapor Deposition), we report on the sudden jumps, bistability, multistability and negative resistance phenomena in methane-hydrogen mixture discharge plasma. We studied the variations of these phenomena with gas pressure, filament current. The difference of discharge characteristic between pure hydroge...

Abstract. This paper deals with the numerical reconstruction of the plasma current density in a Tokamak and of its equilibrium. The problem consists in the identification of a non-linear source in the 2D Grad-Shafranov equation, which governs the axisymmetric equilibrium of a plasma in a Tokamak. The experimental measurements that enable this identification are the magnetics on the vacuum vesse...

In this work, a two-dimensional chemically non-equilibrium (NCE) model has been developed for Ar inductively coupled thermal plasma (ICTP) with C-H-O system at atmospheric pressure from the viewpoint of plasma process and fuel combustion. Chemically non-equilibrium effects have been taken into account by solving mass conservation equations for each of 22 particles (including atoms, molecules, i...

The Lithium Tokamak eXperiment is a spherical tokamak with a close-fitting low-recycling wall composed of thin lithium layers evaporated onto a stainless steel-lined copper shell. Long-lived non-axisymmetric eddy currents are induced in the shell and vacuum vessel by transient plasma and coil currents and these eddy currents influence both the plasma and the magnetic diagnostic signals that are...

The relation between collective properties and performance of antiagglomerants (AAs) used in hydrate management is handled using molecular dynamics simulations and enhanced sampling techniques. A thin film of AAs adsorbed at the interface between one flat sII methane hydrate substrate and a fluid hydrocarbon mixture containing methane and n-dodecane is studied. The AA considered is a surface-ac...

Classical equilibrium molecular dynamics (MD) simulations have been performed to investigate the computational performance of the Simple Point Charge (SPC) and TIP4P water models applied to simulation of methane hydrates, and also of liquid water, on a variety of specialised hardware platforms, in addition to estimation of various equilibrium properties of clathrate hydrates. The FPGA-based acc...
