Based on realistic Monte-Carlo simulations a two-stage beam collimation system is designed to minimize the beam loss in the Fermilab Tevatron for fixed target and collider Run II. Thin primary collimators are used to increase particle amplitude and their impact parameter on the down-stream secondary collimators. This results in a significant reduction of the total beam loss in the machine, decreases collimator overheating and mitigates requirements to colli-mator alignment. A set of collimators will originally be in-stalled for fixed target operation and for antiprotonbeam re-cycling studies. The collimation system improvement will continue into the collider Run II and intensity upgrade.
