Topology of the warm plasma dispersion relation at the second harmonic electron cyclotron resonance layer

Study of Plasma Start-up Initiated by Second Harmonic Electron Cyclotron Resonance Heating on WEGA Experiment

Although both 1 harmonic ordinary mode (O1) and 2 harmonic extra-ordinary mode (X2) have been successfully used to initiate pre-ionization and breakdown in many devices, a complete theoretical model is still missing to explain the success of this method. Moreover, some experimental observations are not completely understood, such as what occurs during the delay time between the turn-on of ECRH ...

TE 01 Excitation of an Electron Cyclotron Resonance Plasma Source

The uniformity of plasma generation in electron cyclotron resonance (ECR) reactors for materials processing, and the subsequent uniformity of fluxes to the substrate, are generally a function of the mode of the microwave radiation injected into the chamber. In this paper, a finite difference time domain (FDTD) simulation is used to demonstrate the consequences of exciting an ECR reactor using a...

Plasma expansion from a dielectric electron cyclotron resonance source

The boundary conditions in an electron cyclotron resonance (ECR) source have been modified to mimic the operating conditions where current-free double-layers (DLs) have been recently measured in rf helicon plasmas. The plasma is heated or generated by the ECR at 875 G inside a dielectric source tube, and expands into a grounded diffusion chamber (terminated by a glass plate) by a rapidly decrea...
