Accelerators and national security the evolution of science policy for high‐energy physics, 1947–1967

Abstract

Historical analysis of the evolution of science policy for high‐energy physics from 1947–1967 shows how national security concerns played a role in this branch of fundamental science. The Manhattan Engineer District (MED) of the U.S. Army Corps of Engineers supported particle accelerators after World War II demonstrated the military utility of particle accelerator technology for isotope separation, the transferability of technological skills from accelerator building to other technologies such as radar development, and the usefulness of particle accelerators in making the physical measurements required in the early stages of the design of nuclear weapons. Although the Atomic Energy Commission initially was disinclined to support further particle accelerator development, it was persuaded to support accelerator projects to advance understanding of the nuclear forces that underlay fission and other nuclear processes, to promote the health of the AEC Laboratories, and to ensure a supply of trained scientific personnel. The bond between accelerator development and national security tightened during the Korean War an AEC‐Department of Defense (DoD) program studied uses of accelerators for defense and to produce nuclear materials. Accelerators contributed to another form of national security: national prestige in the international technological competition with the Soviet Union under the Atoms for Peace program and after the President's Scientific Advisory Committee (PSAC) was created in 1958 to respond to Sputnik. Particle accelerators also continued to develop in the AEC weapons laboratories up to the new emphasis placed on them by the Strategic Defense Initiative Organization (SDIO). Links to national security concerns helped programs traditionally thought to be “pure” science efforts win support, and applications from such programs found their way into applied programs.
