Effects of the extraction voltage applied by the puller-electrode on the H$^−$ extraction in the Linac4 negative ion source
/ Abe, S (Keio U.) ; Nishioka, S (Keio U.) ; Mattei, S (CERN) ; Hatayama, A (Keio U.) ; Lettry, J (CERN)
In order to understand the H$^−$ extraction mechanism and investigate the effect of the extraction voltage applied by the puller-electrode on the H$^−$ extraction in the Linac4 negative ion source, we are developing a 2D3V-PIC (two dimensions in the real space and three dimensions in the velocity space, Particle in Cell) model with volume produced H$^−$ ions. It is shown that how to take the magnetic filter field direction is important for the 2D modeling to take into account the important 3D effect of electron $E \times B$ drift. [...]

Numerical simulation of the RF plasma discharge in the Linac4 H$^−$ ion source
/ Mattei, S (CERN ; CRPP, Lausanne) ; Nishida, K (Keio U.) ; Onai, M (Keio U.) ; Lettry, J (CERN) ; Tran, M Q (CRPP, Lausanne) ; Hatayama, A (Keio U.)
This paper presents a Particle-In-Cell Monte Carlo Collision simulation of the Radio-Frequency (RF) plasma heating in the Linac4 H$^−$ ion source at CERN. The model self-consistently takes into account the electromagnetic field generated by the RF coil, the external static magnetic fields and the resulting plasma response, including a kinetic description of the charged species (e$^−$, H$^+$, H$^+_2$, H$^+_3$, H$^−$), as well as the atomic and molecular (vibrationally resolved) populations.

Influence of the cusp field on the plasma parameters of the Linac4 H− ion source
/ Briefi, S (U. Augsburg (main)) ; Mattei, S (CERN) ; Lettry, J (CERN) ; Fantz, U (U. Augsburg (main) ; Garching, Max Planck Inst. Plasmaphys.)
When the H$^−$ ion source of CERN’s Linac4 is operated in volume mode, a maximum of the extracted current is obtained at varying RF power. The power required for this maximum and its absolute value is strongly influenced by the cusp magnets installed at the source for electron confinement: without magnets, 15−20 mA are typically obtained at 20 kW whereas with magnets a factor of two more power is needed and 25−30 mA are achieved.
