Colliding beam parameters & Overview The Tevatron antiproton collider achieved peak a luminosity of 2.5xl0 31 crn-2 sec-1 in Run I, which ended in February 1996. The Main Injector and associated upgrades are expected to enable luminosities in the range of 5-8Xl0 32 crn-2 sec-1 in Run II, which is scheduled to begin in ****DRAFT VERSION ****-4-****DRAFT VERSION**** * In those 10 weeks 5.7xl0 13 antiprotons were accumulated and 32 pb-1 were deliverd to each of the two experiments. ****DRAFT VERSION ****-7-****DRAFT VERSION****
