PlasmaのCyclotron Resonance (III)

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...

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...

Cyclotron resonance phenomena in a non-neutral multispecies ion plasma

Cyclotron modes of a non-neutral Mg ion plasma were studied in a long cylindrical PenningMalmberg trap. Several modes with angular dependence exp(iZ@, 12 1, are observed near the cyclotron frequencies of the various Mg ions. The I= 1 modes for the majority species are downshifted from the cyclotron frequencies, with downshifts as large as four times the diocotron frequency. These large shifts a...

Cyclotron Resonance and Quasiparticles

This introductory paper contains personal perspectives about the importance of cyclotron resonance in forming our modern view of solids. The papers following this one will discuss the discovery, refinements, and some of the latest developments. Although I will touch on some of these subjects, I leave the details to the other authors and in the main focus on the conceptual impact of the work. I ...
