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…
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…
Reconstruction of energy and angle distribution function of surface-emitted negative ions in hydrogen plasmas using mass spectrometry
D. Kogut, K. Achkasov, J. Dubois +5
A new method involving mass spectrometry and modelling is described in this work, which may highlight the production mechanisms of negative ions on surface in low pressure plasmas.…
