Bremsstrahlung Emission of an X-Band Permanent Magnet Minimum-B Quadrupole Electron Cyclotron Resonance Ion Source
Tarvainen, Olli; Toivanen, Ville; Kalvas, Taneli; Koivisto, Hannu A.; Kosonen, Sami (Institute of Electrical and Electronics Engineers (IEEE), 2024)We have carried out bremsstrahlung measurements on a permanent magnet minimum-B quadrupole electron cyclotron resonance (ECR) ion source operating at 10.3–11.5 GHz microwave frequencies. The bremsstrahlung spectral temperature ... -
Measurement of the energy distribution of electrons escaping minimum-B ECR plasmas
Izotov, Ivan; Tarvainen, Olli; Skalyga, Vadim; Mansfeld, Dmitry; Kalvas, Taneli; Koivisto, Hannu; Kronholm, Risto (IOP Publishing, 2018)The measurement of the electron energy distribution (EED) of electrons escaping axially from a minimum-B electron cyclotron resonance ion source (ECRIS) is reported. The experimental data were recorded with a room-temperature ... -
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 ... -
Effects of magnetic configuration on hot electrons in a minimum-B ECR plasma
Li, Jibo; Li, lixuan; Bhaskar, Bichu; Toivanen, Ville; Tarvainen, Olli; Hitz, Denis; Li, Libin; Lu, Wang; Koivisto, Hannu; Thuillier, Thomas; Guo, Junwei; Zhang, Xuezhen; Zhao, Huanyu; Sun, Lingting; Zhao, Hongwei (IOP Publishing, 2020)To investigate the hot electron population and the appearance of kinetic instabilities in highly charged electron cyclotron resonance ion source (ECRIS), the axially emitted bremsstrahlung spectra and microwave bursts ... -
