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 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...
متن کاملGas Flow Influence on Negative Hydrogen Ion Generation within the Microwave-driven Negative Ion Source*
H ion was generated through two processes within a volume Csfree source. The density of molecule hydrogen gas will impact on the electron temperature within the primary discharge chamber that will influence the population of vibrational excited H2. Within the extraction region, the interaction between molecule hydrogen and H ion will is cause the dissociation of negative ion. To better understa...
متن کاملStatus of the J-parc Negative Hydrogen Ion Source
A cesium-free negative hydrogen ion source driven with a LaB6 filament is being operated for J-PARC. The beam commissioning of J-PARC accelerators started in November 2006. As of June 2010, there have been 34 beam commissioning or supply runs. In these runs, the ion source has been successfully operated in two different modes such as low current mode of 5 mA and high current mode of 30 mA. Acco...
