Numerical study of the plasma meniscus shape and beam optics in RF negative ion sources / Hayashi, K (Keio U.) ; Hoshino, K (Keio U.) ; Miyamoto, K (Naruto U. of Education) ; Hatayama, A (Keio U.) ; Lettry, J (CERN)
In order to extract intense ion beams with good beam optics from hydrogen negative ionsources, it is important to control the shape of the plasma meniscus (i.e. beam emissionsurface). [...]

Effects of the extraction voltage on the beam divergence for a H$^−$ ion source / Lindqvist, M (Keio U.) ; Nishioka, S (Keio U.) ; Miyamoto, K (Naruto U. of Education) ; Hoshino, K (Keio U.) ; Lettry, J (CERN) ; Hatayama, A (Keio U.)
Negative hydrogen (H$^−$) ion sources have a wide range of applications. The general requirement for these H$^−$ ion sources is to produce intense H$^−$ ion beams with good beam optics. [...]

Analysis of H− extraction in the Linac4 negative ion source by 2.5D particle simulation / Abe, S (Keio U.) ; Nishioka, S (Keio U.) ; Mattei, S (CERN) ; Miyamoto, K (Naruto U. of Education) ; Hatayama, A (Keio U.) ; Lettry, J (CERN)
The purpose of this study is to investigate the extraction mechanisms of the H− ions in the Linac4 negative ion source by using an improved two-dimensional in real space and three-dimensional in velocity space Particle in Cell (2D3V-PIC) model. In this model, the following collision processes of the surface produced H− (Hsp−) ions have been introduced and the effects of the collisions on H− extraction have been analyzed: elastic (Hsp− - H2) and charge exchange (Hsp− - H). [...]

Effect of Coulomb collision on the negative ion extraction mechanism in negative ion sources / Goto, I (Keio U.) ; Miyamoto, K (Naruto U. of Education) ; Nishioka, S (Keio U.) ; Mattei, S (CERN) ; Lettry, J (CERN) ; Abe, S (Keio U.) ; Hatayama, A (Keio U.)
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 collision model.
