Experimental evidence on photo-assisted O ion production from AlO cathode in cesium sputter negative ion source
O. Tarvainen, R. Kronholm, M. Laitinen +8
The production of negative ions in cesium sputter ion sources is generally considered to be a pure surface process. It has been recently proposed that ion pair production could exp…

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…
