When accelerating uranium beam(e.g. 238U³⁵⁺), the variation range of the kinetic energy is 17MeV/u-830 MeV/u, and the corresponding revolution frequency range is 0.099MHz-0.447MHz. Because of the low frequency limit value of 0.099MHz, the RF frequency of RF cavity should be h(harmonic number) times of ,thus, there will have h(is equal to harmonic number) bunches after acceleration. To satisfy the extraction requirement, the accelerated multiple bunches should be recollected in one bunch by means of longitudinal manipulation. The different single bunch generation method of debunching and bunch merging are investigated separately, and the beam parameters in different cases are obtained, meanwhile, the optimized RF program during the debunching and bunch merging are presented.
