• Characteristic Kα emission of electron cyclotron resonance ion source plasmas 

  Sakieldien, Moenir (University of Jyväskylä, 2018)

  This thesis presents the results of an investigation of the volumetric Kα emission rate/inner shell ionization rate from an Electron Cyclotron Resonance Ion Source (ECRIS) plasma tuned predominantly for high charge state ...

• The biased disc of an electron cyclotron resonance ion source as a probe of instability-induced electron and ion losses 

  Tarvainen, O.; Kronholm, R.; Kalvas, T.; Koivisto, H.; Izotov, I.; Skalyga, V.; Toivanen, V.; Maunoury, L. (American Institute of Physics, 2019)

  Electron Cyclotron Resonance Ion Source (ECRIS) plasmas are prone to kinetic instabilities resulting in loss of electron and ion confinement. It is demonstrated that the biased disk of an ECRIS can be used as a probe to ...

• Study of gasdynamic electron cyclotron resonance plasma vacuum ultraviolet emission to optimize negative hydrogen ion production efficiency 

  Lapin, R. L.; Skalyga, V. A.; Izotov, I.; Razin, S. V.; Shaposhnikov, R. A.; Vybin, S. S.; Bokhanov, A. F.; Kazakov, M. Yu.; Tarvainen, O. (American Institute of Physics, 2020)

  Negative hydrogen ion sources are used as injectors into accelerators and drive the neutral beam heating in ITER. Certain processes in low-temperature hydrogen plasmas are accompanied by the emission of vacuum ultraviolet ...

• 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 ...

• Observation of Poincaré-Andronov-Hopf Bifurcation in Cyclotron Maser Emission from a Magnetic Plasma Trap 

  Shalashov, A. G.; Gospodchikov, E. D.; Izotov, I. V.; Mansfeld, D. A.; Skalyga, V. A.; Tarvainen, Olli (American Physical Society, 2018)

  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 ...
