In his opening remarks at the October 26-28, 2009 symposium and workshop on “Accelerators for America’s Future” in Washington D.C., Dennis Kovar, Associate Director of the Office of Science for High Energy Physics, stressed that particle accelerators are major tools for basic and applied sciences and serve the nation and society in many, many ways. Among them he highlighted medical, security and industrial applications, as well as to point out that these “tools” – once the domain of only the physical sciences - are now central resources for advances in biological, chemical and, actually, all the scientific disciplines. As part of its mission to build and operator the Nation’s major user accelerator facilities, the Department of Energy hosted the three day workshop so that it could better understand opportunities for advancements in accelerator technologies and the impacts these advancements could have in basic and applied sciences.

Representing Cornell and CLASSE, Maury Tigner gave an invited presentation entitled “Accelerators - Modern Ships Of Discovery.” He illustrates the story of how accelerators and detectors “take us where we cannot go unaided,” enabling us to see what we cannot see with the particles and light produced by the facilities. He touches upon the past but dwells most on the “ships and adventures that are soon to be launched.” Among the modern ships he talks of particle physics facilities (LHC, CEBAF, and others), accelerators on the near horizon for materials sciences (NSLS-II, LCLS, XFEL), and technologies under development for future facilities (soft x-ray FEL, ERL). He stresses that having future accelerators to support the evolution of sciences depends upon a strong and constant effort to recognize and support of the science of accelerators.
