The Conference was organized by the New York Academy of Sciences.The subjects discussed differed from those normally treated at conferences on nuclear fusion by means of magnetic confinement in toroidal geometry, since the material presented consisted of invited papers (42) describing approaches to the subject of controlled nuclear fusion that are new in concept or in techniques applied as a result of the technological advances made. The Conference had an international character since the main countries where such research is being carried out – Canada, France, the Soviet Union, Sweden and the United States – were represented (about 90 participants). Contributions came from, amongst others, the Naval Research Laboratory at Washington, the United States Air Force Weapons Laboratory at Albuquerque, the Livermore, Los Alamos, Stanford, Cornell, Argonne and Sandia Corporation Laboratories, the Universities of Rutgers (New Brunswick, N. J. ), Wisconsin (Madison), Illinois, North Carolina (Raleigh, N. C. ), Irvine (California), the Stevens Institute of Technology, Oxford (United Kingdom), the Kurchatov, Kharkov, Novosibirsk, Tbilisi Institutes and from the relevant departments of the Canadian, French and United States Atomic Energy Commissions.
