Size Scaling of Negative Hydrogen Ion Sources for Fusion
The RF-driven negative hydrogen ion source (H , D ) for the international fusion experiment ITER has a width of 0.9 m and a height of 1.9 m and is based on a scale prototype source being in operation at the IPP test facilities BATMAN and MANITU for many years. Among the challenges to meet the required parameters in a caesiated source at a source pressure of 0.3 Pa or less is the challenge in si...
متن کاملReview of Negative Hydrogen Ion Sources High Brightness/high Current
Due to the development of reliable H ion sources, charge-exchange injection into circular accelerators has become routine. This paper reviews recent developments in negative hydrogen ion sources. The underlying physics, operating parameters and beam characteristics of selected sources will be described and compared. Figure 1: History of duoplasmatron and surface source development.
متن کاملMeasurements of Argon-ion Flow in Negative Ion Containing Plasmas
A laser-induced-fluorescence diagnostics was set up for the investigation of ion flows in negative ion containing plasmas. The contingent of negative ions in Ar plasmas is varied by admixing O2. Results on flow measurements in different plasma devices are reported. First measurements were carried out in the linear double-plasma device, in the sheath region in front of an electrically floating p...
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...
