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…
Preferential orientation of NV defects in CVD diamond films grown on (113) substrates
M. Lesik, T. Plays, A. Tallaire +9
Thick CVD diamond layers were successfully grown on (113)-oriented substrates. They exhibited smooth surface morphologies and a crystalline quality comparable to (100) electronic g…
