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…
Enhancing surface production of negative ions using nitrogen doped diamond in a deuterium plasma
Gregory J. Smith, James Ellis, Roba Moussaoui +7
The production of negative ions is of significant interest for applications including mass spectrometry, particle acceleration, material surface processing, and neutral beam inject…
(111)-oriented, single crystal diamond tips for nanoscale scanning probe imaging of out-of-plane magnetic fields
D. Rohner, J. Happacher, P. Reiser +5
We present an implementation of all-diamond scanning probes for scanning nitrogen-vacancy (NV) magnetometry fabricated from (111)-oriented diamond material. The realized scanning p…
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…
Initialization and Readout of Nuclear Spins via negatively charged Silicon-Vacancy Center in Diamond
Mathias H. Metsch, Katharina Senkalla, Benedikt Tratzmiller +7
In this work, we demonstrate initialization and readout of nuclear spins via a negatively charged silicon-vacancy (SiV) electron spin qubit. Under Hartmann-Hahn conditions the elec…
