Surface modification of narra wood (Pterocarpus indicus) by ion shower treatment
(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 ...
Optimized H− extraction in an argon–magnesium seeded magnetized sheet plasma
(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 ...
Extraction and profile analysis of hydrogen-like helium ions in a magnetized sheet plasma
(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, ...
An investigation as to the cause of beam asymmetry in a compact gas discharge ion source: A focus on beam-wall interaction
(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 ...
