DescriptionExperiment and simulation of kinetic instabilities in electron cyclotron resonance mirror plasma
We report observations of electromagnetic emissions at electron cyclotron harmonics in a mirror-confined electron cyclotron resonance (ECR) plasma . The present research has achieved a new understanding of electron cyclotron instabilities by comparing measurements of emissions from a well-diagnosed laboratory plasma, with the predictions of analytical theory supported by Vlasov simulations. A notable success of this work is the revelation of the subtle effects that the presence of multi-component electron distribution functions involving a warm and ring-distributed  200-400 eV mirror-confined population of electrons and a much colder 1 eV component have on the excitation of electron cyclotron instabilities, where the instability takes place at frequencies near the upper hybrid frequency of the cold component.
