Thermal Plasma Source of Hydrogen Atoms and Ions
نویسندگان
چکیده
A cascade arc is used as a source for a hydrogen/argon particle beam. The plasma is produced at thermal plasma conditions in the pressure range of 0.1 to 1 bar. It is expanded with a high velocity into a vacuum chamber. Measurements with a Langmuir double probe and with a mass spectrometer are performed. The resulting parameters of the plasma and the extracted ions are discussed. Molecular processes as charge exchange and dissociative recombination appear to be important.

Cell damaging by irradiating non-thermal plasma to the water: Mathematical modeling of chemical processes
Recently non-thermal plasma (NTP) is applied for many therapeutic applications. By NTP irradiating to the tissues or cell-lines, the water molecules (H2O) would be also activated leading to generate hydrogen peroxide (H2O2). By irradiating plasma to bio-solution, its main output including vacuum UV to UV causes the photolysis of H2O leading to generat...
متن کاملSheath structure in negative ion sources for fusion (invited).
In fusion negative ion sources, the negative ions are formed on the caesiated plasma grid predominantly by hydrogen atoms from the plasma. The space charge of the negative ions leaving the wall is not fully compensated by incoming positive ions and at high enough emission a virtual cathode is formed. This virtual cathode limits the flux of negative ions transported across the sheath to the plas...
متن کاملFormation of a Hydrogen Plasma from an Incandescently Heated Hydrogen-Catalyst Gas Mixture with an Anomalous Afterglow Duration
We report the generation of a plasma of hydrogen and certain alkali ions as recorded via EUV spectroscopy and the hydrogen Balmer and alkali line emissions in the visible range. Typically a hydrogen plasma is generated and the emission of extreme ultraviolet light from hydrogen gas is achieved via a discharge at high voltage, a high power inductively coupled plasma, or a plasma created and heat...
متن کاملHydrogen pair-ion production by catalytic ionization
Pair plasmas consisting of only positiveand negative-charge particles of equal mass have attracted special attention because they maintain space-time symmetry. A fullerene pair-ion plasma, consisting of positive and negative ions of equal mass (C60 and C60), has been generated and its collective phenomena have been investigated experimentally [1]. In order to investigate more extensive physical...
متن کاملMolecular Dynamics Study on Behavior of Hydrocarbon Molecules in Hydrogen Atom Gas
Carbon chains are produced from a graphite (0 0 0 1) surface due to hydrogen atom sputtering. The carbon chains do chemical reaction with hydrogen ion in edge plasma. In this paper, the chemical reaction of the carbon chains in the hydrogen atom gas, which substitutes for hydrogen plasma, was investigated by the use of molecular dynamics simulation with modified Brenner reactive empirical bond ...
