We are here today to discuss the means by which the development of advanced accelerator facilities can best implement the further exploration of highenergy phenomena. I shall refrain from showing a chart of the type that purports to indicate, by a double‐logarithmic plot of available energy vs time, that accelerators of increasingly high energy areinevitable. We might, however, recall the recommendations that the Ramsey Panel submitted a year ago to the Atomic Energy Commission's General Advisory Committee and to the President's Office of Science and Technology. Figure 1 is adopted from a similar diagram in the report of this Panel, whose recommendations with respect to the new facilities required to insure continued progress in high‐energy physics clearly attached highest importance to advancement of the “energy frontier.”
