Method for estimating charge breeder ECR ion source plasma parameters with short pulse 1+ injection
J. Angot, M. Luntinen, T. Kalvas +6
A new method for determining plasma parameters from beam current transients resulting from short pulse 1+ injection into a Charge Breeder Electron Cyclotron Resonance Ion Source (C…
Controlled turbulence regime of electron cyclotron resonance ion source for improved multicharged ion performance
V. A. Skalyga, I. V. Izotov, A. G. Shalashov +5
Fundamental studies of excitation and non-linear evolution of kinetic instabilities of strongly nonequlibrium hot plasmas confined in open magnetic traps suggest new opportunities…
Measurements of the energy distribution of electrons lost from the minimum B-field -- the effect of instabilities and two-frequency heating
Ivan Izotov, Olli Tarvainen, Vadim Skalyga +5
Further progress in the development of ECR ion sources (ECRIS) requires deeper understanding of the underlying physics. One of the topics that remains obscure, though being crucial…
The role of rf-scattering in high-energy electron losses from minimum-B ECR ion source
I. V. Izotov, A. G. Shalashov, V. A. Skalyga +7
The measurement of the axially lost electron energy distribution escaping from a minimum-B electron cyclotron resonance ion source in the range of 4-800 keV is reported. The experi…
VUV diagnostic of electron impact processes in low temperature molecular hydrogen plasma
J. Komppula, O. Tarvainen
Novel methods for diagnostics of molecular hydrogen plasma processes, such as ionization, production of high vibrational levels, dissociation of molecules via excitation to singlet…
Photoelectron Emission from Metal Surfaces Induced by VUV-emission of Filament Driven Hydrogen Arc Discharge Plasma
J. Laulainen, T. Kalvas, H. Koivisto +2
Photoelectron emission measurements have been performed using a filament-driven multi-cusp arc discharge volume production H^- ion source (LIISA). It has been found that photoelect…
