Simulation study of the RF chopper

Kondo, Yasuhiro ; Ikegami, Masanori*; Naito, Fujio*; Qiang, J.*

For the beam current upgrade of the J-PARC linac, a new RFQ (RFQ III) is developing. The peak beam current of RFQ III is 50 mA. To increase the peak current form the existing RFQ (RFQ I), the longitudinal and/or transverse emittances are expected to be increased. However, the increase of the longitudinal emittance will affect the performance of the RF chopper system. In this paper, detailed simulations of the RF chopper system are described.
