Accelerator Science at Fermilab and the World

This talk gives an overview of the forefront accelerator technology R&D that is being conducted at Fermilab and other national laboratories. It will include the dramatic leaps in superconducting RF technology, that enable a series of highly efficient user facilities in Basic Energy Sciences, Nuclear physics, Fusion and High Energy Physics. In parallel, highly efficient RF power sources extending into terahertz frequencies are being developed. Together with other technologies these developments also provide the necessary groundwork for a wide range of accelerator applications, energy production, nuclear transmutation and medical therapy.
