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…
R&D around a photoneutralizer-based NBI system (Siphore) in view of a DEMO Tokamak steady state fusion reactor
A. Simonin, Jocelyn Achard, K. Achkasov +28
Since the signature of the ITER treaty in 2006, a new research programme targeting the emergence of a new generation of Neutral Beam (NB) system for the future fusion reactor (DEMO…
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…
Pulsed DC bias for the study of negative-ion production on surfaces of insulating materials in low pressure hydrogen plasmas
K. Achkasov, R. Moussaoui, D. Kogut +7
In this work negative-ion production on the surface of a sample negatively DC biased in a hydrogen plasma is studied. The negative ions created under the positive ion bombardment a…
