The recent measurements of the antiproton yield as well as the previous ones differ from the predictions which are the basis of the TEVATRON1 Design Report. It was found in reference that at small acceptances, where the data depends essentially only on the forward pbar production cross section, the measured yield data indicates that these cross sections were over estimated by about a factor of 3 in the case of tungsten and about 2.3 in the case of copper. To clear up the situation and to understand what one can do to maximize the luminosity of the TEVATRON Collider this work has been done. Two sides of the antiproton production problem are considered: pbar production cross sections and targeting limitations. Energy deposition density distributions in targets and particle yields are studied via Monte Carlo hadronic and electromagnetic cascade calculations. In the present work we use two independent Monte Carlo programs.
