CDF results on diffraction from Run I and plans for Run II

Abstract

Results on soft and hard diffraction obtained by the CDF Collaboration in Run I of the Fermilab Tevatron pbar-p collider are reviewed and compared with results from the DESY e-p collider HERA and with theoretical expectations. In addition, the CDF program for diffractive studies in Run II is briefly reviewed with emphasis on the relevant detector upgrades and physics goals.
