| Abstract
The p pbar data at sqrt(s)=1800 GeV taken with the CDF detector
including a Roman Pot tracking system are used to determine the
diffractive structure of the proton. Comparison with the diffractive
structure measured in deep-inelastic scattering by the H1 Collaboration
indicates a breakdown of factorization.
The results from events with rapidity-gaps on both the proton and
anti-proton sides (double Pomeron exchange) are also presented.
