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 ... -
Efficiency investigation of a negative hydrogen ion beam production with the use of the gasdynamic ECR plasma source
Lapin, R. L.; Skalyga, V. A.; Izotov, I. V.; Golubev, S. V.; Razin, S. V.; Bokhanov, A. F.; Kazakov, M. Yu.; Shaposhnikov, R. A; Kiseleva, E. M.; Tarvainen, O. (IOP Publishing, 2020)Negative hydrogen ion sources are of great demand in modern physics as injectors into accelerators and drivers for neutral beam injectors for fusion devices. It has been shown earlier that the use of the gasdynamic ECR ... -
Slit extraction and emittance results of a permanent magnet minimum-B quadrupole electron cyclotron resonance ion source
Kosonen, Sami; Kalvas, Taneli; Koivisto, Hannu; Tarvainen, Olli; Toivanen, Ville (Elsevier, 2024)We present an experimental and simulation study of high charge state ion beams produced with a permanent magnet electron cyclotron resonance ion source (ECRIS) with minimum-B quadrupole magnetic field topology and slit ... -
Quasi-periodical kinetic instabilities in minimum-B confined plasma
Bhaskar, B. S.; Koivisto, H.; Tarvainen, O.; Thuillier, T.; Toivanen, V. (AIP Publishing, 2022)We present the results of an experimental investigation of quasi-periodical kinetic instabilities exhibited by magnetically confined electron cyclotron resonance heated plasmas. The instabilities were detected by measuring ... -
Status of new developments in the field of high-current gasdynamic ECR ion sources at the IAP RAS
Skalyga, V. A.; Golubev, S. V.; Izotov, I. V.; Kazakov, M. Yu.; Lapin, R. L.; Razin, S. V.; Sidorov, A. V.; Shaposhnikov, R. A.; Bokhanov, A. F.; Tarvainen, Olli (AIP Publishing, 2018)The experimental and theoretical research carried out in the past at the Institute of Applied Physics (IAP RAS) resulted in development of a new type of electron cyclotron resonance ion source (ECRIS) – the gasdynamic ...
