I describe here very promising schemes for producing high intensity low longitudinal emittance proton bunches for proton-antiproton collider operation in the Tevatron. These methods are based on the use of wide-band barrier rf systems in the Main Injector. The beam dynamics simulations clearly suggest that these schemes allow a wide range of bunch intensities and longitudinal emittances. I also discuss a method, called “27 GeV coalescing”, which is a spin-off from 2.5 MHz pbar acceleration scheme demonstrated in the Main Injector (MI). Preliminary results from beam study for this scheme are presented. In this paper I present the principle of these methods and results of multi-particle beam dynamics simulations.
