Description
The J-PARC MR receives a high intensity beam from the RCS and accelerates it up to 30 GeV. The designed longitudinal emittance of the RCS under the normal acceleration pattern is 5 eVs, where as up to 10 eVs is accepted in the MR. Since a large emittance is needed for slow extraction operation at the MR flat top to mitigate a microwave instability, the emittance should be increased before the MR flat top is reached. We have investigated the controlled longitudinal beam emittance blow-up using the phase modulation during the MR acceleration period by a particle tracking code. (author)
