Optimized H− extraction in an argon–magnesium seeded magnetized sheet plasma

Noguera, Virginia R.; Blantocas, Gene Q.; Ramos, Henry J. (Elsevier B.V., 2008-06)

The enhancement and optimization of H− extraction through argon and magnesium seeding of hydrogen discharges in a magnetized sheet plasma source are reported. The paper first presents the modification of the production ...

An investigation as to the cause of beam asymmetry in a compact gas discharge ion source: A focus on beam-wall interaction

Blantocas, Gene Q.; Ramos, Henry J.; Wada, Motoi (IOP Publishing; The Japan Society of Applied Physics, 2006-10-24)

Helium beams in a compact gas discharge source lose their transverse symmetry when the extracting electrode is biased at high potentials. Further, this condition gives rise to excessive formation of electrons within the ...

Extraction and profile analysis of hydrogen-like helium ions in a magnetized sheet plasma

Blantocas, Gene Q.; Ramos, Henry J.; Wada, Motoi (American Institute of Physics, 2002-02)

The extraction of He+ ions from a magnetized sheet plasma source is reported. Optimum detection and extraction of He+ ions were conducted using an E×B probe as a mass analyzer. The effect of the probe’s extraction potential, ...

Surface modification of narra wood (Pterocarpus indicus) by ion shower treatment

Blantocas, Gene Q.; Ramos, Henry

; Wada, Motoi

(Japanese Journal of Applied Physics, 2006-10-24)

A gas discharge ion source (GDIS) was used as test facility to produce and study the characteristics of diffused, low-energy hydrogen ion showers. Narra wood samples were then exposed to the showers to investigate topographical ...
