Surface production of negative ions from pulse-biased nitrogen doped diamond within a low-pressure deuterium plasma
Gregory J. Smith, Lenny Tahri, Jocelyn Achard +4
The production of negative ions is of significant interest for applications including mass spectrometry, materials surface processing, and neutral beam injection for magnetic confi…
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…
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…
Diagnostics of low-pressure hydrogen discharge created in a 13.56 MHz RF plasma reactor
J Krištof, A Annušová, M Anguš +5
A 13.56 MHz RF discharge in hydrogen was studied within the pressure range of 1-17 10 Pa, and at power range of 400-1000 W. The electron energy distribution function and 18 electro…
