Stabilization of beam instability due to space-charge effects at J-PARC

Shobuda, Yoshihiro ; Chin, Y. H.*; Toyama, Takeshi*; Ikegami, Masanori*

The kicker magnet is one of dominant sources of impedances with 3 GeV RCS at J-PARC. It has been considered that this impedance gives us the significant constraint to increase the beam intensity. Recently, the 300 kW beam was accomplished at 3 GeV RCS, while no instability is found. We discuss the space charge effect to stabilize the beam instability.
