We report the first experimental evidence of a controlled transition from the generation of periodic bursts of electromagnetic radiation into the continuous-wave regime of a cyclotron maser formed in magnetically confined nonequilibrium plasma. The kinetic cyclotron instability of the extraordinary wave of weakly inhomogeneous magnetized plasma is driven by the anisotropic electron population resulting from electron cyclotron plasma heating in a MHD-stable minimum-B open magnetic trap.

Plasma diagnostic tools for ECR ion sources : What can we learn from these experiments for the next generation sources

Tarvainen, O.; Kalvas, T.; Koivisto, H.; Kronholm, R.; Marttinen, M.; Sakildien, M.; Toivanen, V.; Izotov, I.; Skalyga, V.; Angot, J. (American Institute of Physics, 2019)

The order-of-magnitude performance leaps of ECR ion sources over the past decades result from improvements to the magnetic plasma confinement, increases in the microwave heating frequency, and techniques to stabilize the ...
Influence of axial mirror ratios on the kinetic instability threshold in electron cyclotron resonance ion source plasma

Toivanen, V.; Bhaskar, B. S.; Koivisto, H.; Maunoury, L.; Tarvainen, O.; Thuillier, T. (American Institute of Physics, 2022)

Electron Cyclotron Resonance (ECR) ion source plasmas are prone to kinetic instabilities. The onset of the instabilities manifests as emission of microwaves, bursts of electrons expelled from the plasma volume, and the ...
