AMANDA-II, the second phase of the AMANDA program to detect high energy neutrinos from astrophysical sources was completed in February, 2000 and has taken data routinely since that time. About one year later, during the next Antarctic campaign, detector calibration studies were performed. This paper outlines the scientific program of the AMANDA-II detector and describes the potential contribution to each goal. Detector performance, such as the effective area as a function of muon energy and zenith angle and angular resolution, is used to estimate the minimum detectable flux for several specialized analysis procedures. Assuming several years of livetime, AMANDA-II has the capability to observe neutrino fluxes from diffuse and point sources that are at least an order of magnitude below current limits, and in the case of diffuse sources, reach background limited operation for neutrino energies below ˜ 102 TeV. The time-integrated effective volume for muon neutrino detection is expected to reach 1 km3 yr for Eν > 102 TeV. Atmospheric neutrinos will provide a high statistics calibration of the detector performance from zenith to near the horizon. At EHE energies, the muons produced by νµ interactions can be differentiated from atmospheric muons. The exposure of AMANDA-II approaches 1 km2 yr for Eµ > 108 TeV.
