Impact of positive ion energy on carbon-surface production of negative ions in deuterium plasmas
D. Kogut, R. Moussaoui, Ning Ning +6
This work focuses on the production of negative-ions on graphite and diamond surfaces bombarded by positive ions in a low pressure (2 Pa) low power (20 W) capacitively coupled deut…
Negative-hydrogen-ion production from a nanoporous 12CaO 7Al2O3 (C12A7) electride surface
Mamiko Sasao, Roba Moussaoui, Dmitry Kogut +5
A high production rate of negative hydrogen ion was observed from a nanoporous C12A7 electride surface immersed in hydrogen/deuterium low-pressure plasmas. The target was biased at…
Negative-ion surface production in hydrogen plasmas: Determination of the negative-ion energy and angle distribution function using mass spectrometry
J. Dubois, K. Achkasov, D. Kogut +4
This work focuses on the understanding of the production mechanism of negative-ions on surface in low pressure plasmas of H2/D2. The negative ions are produced on a HOPG sample (Hi…
Alternative solutions to caesium in negative-ion sources: a study of negative-ion surface production on diamond in H 2 /D 2 plasmas
Gilles Cartry, Dmitry Kogut, Kostiantyn Achkasov +9
This paper deals with a study of H-/D-negative ion surface production on diamond in low pressure H2/D2 plasmas. A sample placed in the plasma is negatively biased with respect to p…
Single-crystal and polycrystalline diamond erosion studies in Pilot-PSI
D. Kogut, D. Aussems, N. Ning +9
Diamond is a promising candidate for enhancing the negative-ion surface production in the ion sources for neutral injection in fusion reactors; hence evaluation of its reactivity t…
