The Emerging Strategic Balance
light. Indubitably the strategic balance between the two super powers is the most important strategic equation obtaining today. What differentiates the nuclear forces of the super powers from other nuclear powers is not the overwhelmingly larger number of atomic weapons available with them, but their technological capability quickly to reach higher levels of sophistication which can be attained by other nuclear powers only with very great difhculty. Besides intercontinental missiles (ICBMs), multiple warhead systems (MIRVs) and anti-ballistic missile (ABM) systems, they have at present reconnaissance satellites, communication satellites and satellite inter-
A Multi-Bloc Model of The International System
This essay will attempt to define an abstract model of the international system (or, more precisely, a model of the structure of that system), as a supplement to the types presented by Morton A. Kaplan. Before attempting such a construction, it is well to show the utility of the “multi-bloc system” as an alternative to his six models. Kaplan's “balance-of-power” and “unit veto” systems are essentially defined in terms of nation-states as “actors”; and his “universal” and “hierarchical” systems have essentially but one “actor,” though in the former the nation-state subsists as an administrative and local political unit. The two “bipolar” models (“loose” and “tight”) have, by definition, two major bloc “actors,” with uncommitted nation-states on the margin and an “international actor” such as the U.N. playing a limited role in the former model. It is true that his “unit veto” system may have blocs instead of nation-states for “actors,” but by this very token the difference between a system with a multiplicity of states and one with a multiplicity of blocs is not suggested by Kaplan's typology. The possibility of an international system composed of a multiplicity of blocs has been considered by a number of writers in the past few years. Even before the end of the Second World War, Walter Lippmann wrote: The question is whether some sixty to seventy states, each acting separately, can form a universal organization for the maintenance of peace. I contend that they cannot, and that single sovereign states must combine in their neighborhoods, and that the neighborhoods must combine into larger communities and constellations, which then participate in a universal society.
Long Ceramic Beam Tubes for Accelerator Magnets
The ceramic beam tubes for the fast and abort kickers and the bucker and pinger magnets used at Fermilab must meet a number of exacting requirements. The tubes must be long and sufficiently straight so as not to limit magnet design. They must have wall strength capable of withstanding the atmospheric and mechanical forces encountered during construction and operation. Vacuum tight ceramic to stainless steel transitions must be of reasonable cost; they must also withstand high temperature processing and remain vacuum tight to the 10/sup -9/ Torr range. To remove the possibility of static charge buildup each tube must have a surface coating of indium oxide applied to the inner wall. This thin coating is difficult to achieve and requires the most careful attention to detail. The methods used at Fermilab to achieve these goals are presented in this paper.
