Pion yield dependence on beta function at the target was simulated for different setups. It is shown that yield from current pbar target can be enlarged on about 70% by decreasing proton beam size from 0.55 to 0.15 mm. Yield can be incresed on 40% by using cylinderical target with radius about 2.5 proton beam rms and thickness 0.3-0.5 interaction length.
