Volume Production of D Negative Ions in Low-Pressure D2 Plasmas - Negative Ion Densities versus Plasma Parameters -
Volume production of D negative ions including isotope effects is studied in a rectangular arc chamber. Production and control of plasma parameters in D2 plasmas are performed by varying the intensity of the magnetic filter. The values of Te and ne in D2 plasmas are slightly higher than ones in H2 plasmas. Te in D2 plasmas cannot be decreased and is kept above 1 eV in the extraction region with...

متن کاملRelationship between production and extraction of D/H negative ions in a volume negative ion source
Pure volume production of D negative ions is studied in rectangular negative ion source equipped with an external magnetic filter (MF). Production and control of D2 plasma with the MF is nearly the same as that of H2 plasmas. Plasma parameters (ne and Te) in D2 plasmas are varied mainly in the downstream region by changing the magnetic field intensity of the MF (i.e., BMF), although the values ...
متن کاملSpatial variation of negative ion density in a volume H- ion source
2014 The density distribution of negative hydrogen ions along the axis of a hybrid multicusp Hion source was measured, at different pressures, by using the photodetachement technique. It was found that in the region close to the plasma electrode (first electrode of the extractor) the negative ion density is strongly influenced by the stray magnetic field of the extractor magnets. This stray mag...
متن کاملEffect of Coulomb collision on the negative ion extraction mechanism in negative ion sources.
To improve the H(-) ion beam optics, it is necessary to understand the energy relaxation process of surface produced H(-) ions in the extraction region of Cs seeded H(-) ion sources. Coulomb collisions of charged particles have been introduced to the 2D3V-PIC (two dimension in real space and three dimension in velocity space particle-in-cell) model for the H(-) extraction by using the binary co...
