Toward an improved risk/crisis communication in this time of COVID-19 pandemic: A baseline study for Philippine local government units
(Scuola Internazionale Superiore di Studi Avanzati (SISSA) Medialab, 2020-12-14)
This study mainly explores the communication preferences of the public; their level of trust in the government; and the factors affecting their risk/crisis perception amidst the COVID-19 pandemic. The key findings — derived ...
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 ...
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 ...
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, ...
