Using 100 kV R.F. system, the beam loss due to transition crossing can be reduced to 1% for the phase space area of 0.3ev /center dot/ sec/amu. However the space charge effect would increase the phase space area to 1ev /center dot/ sec/amu after the transition energy. By using ..gamma../sub t/ jump or ..gamma.. increase, the phase space area can be preserved to 0.3ev /center dot/ sec/amu. To obtain small bunch length at the collision energy, we study the bunch rotation scheme. We find that the R.F. harmonic number should be less than 6 x 342 to obtain good efficiency and larger than 4 x 342 to reach experimental requirement. 5 refs., 13 figs., 2 tabs.
