Mathematical models and illustrative results for the RINGBEARER II monopole/dipole beam-propagation code

Description: RINGBEARER II is a linearized monopole/dipole particle simulation code for studying intense relativistic electron beam propagation in gas. In this report the mathematical models utilized for beam particle dynamics and pinch field computation are delineated. Difficulties encountered in code operations and some remedies are discussed. Sample output is presented detailing the diagnostics and the methods of display and analysis utilized.

Graph-theoretic algorithm for hierarchial decomposition of dynamic systems

Description: A graph-theoretic scheme is proposed for partitioning of dynamic systems into hierarchially ordered subsystems having independent inputs and outputs. The resulting subsystems are input-output reachable as well as structurally controllable and observable, so that a piece-by-piece design of estimators and controllers can be accomplished for systems with large dimensions without excessive computer requirements.

Finite-element stress and deflection analysis of CDF yoke and end plug

Description: A large detector is being designed to study anti pp collisions at center-of-mass energies of up to 2000 GeV as part of the Fermilab Collider Detector Facility (CDF). The central detector of this facility consists of a solenoid, calorimeter yoke, and a variety of particle measurement devices. The yoke will be a large steel structure that will provide the magnetic flux return path as well as support structure for calorimetry and other instrumentation. It must resist both electromagnetic and gravi… more

General formalism for the study of activation: application to radiochemical detectors

Description: This paper develops mathematical techniques required for the study of neutron-induced activation of importance to fission and fusion devices - reactors, nuclear weapons, etc. The formalism is presented as a guide for examining the dependence of activation products on flux time history, spatial gradients and the sensitivity to the assumed reactions and cross sections. Exact solutions in powers of the neutron fluence are presented and examined in various limits. As an example, radiochemical thres… more

TMX-Upgrade (TMX-U) operation in the sloshing-ion mode

Description: This report summarizes initial results from TMX-U carried out from June through August 1982. In these successful experiments we operated TMX-U in the sloshing-ion mode. We generated sloshing ions, measured improved energy confinement, and observed improved microstability compared to TMX. The experiments operated about as we expected and we are pleased with the results. During this period many additional achievements were also recorded. The magnetically confined sloshing ions constitute one of t… more

TeVatron I Small-Aperture Quad lamination analysis

Description: Stacking, compression, and welding of the laminations for the TeV I Small Aperture Quad results in a deformation due to springback which is unacceptable due to magnetic field requirements. ANSYS has been used to analyze a solution to this problem.

Human Rights and U.S. Foreign Policy

Description: Following a review of such broad policy issues, this report treats specific human rights issues of current interest. Discussions of controversy over the selection of an Assistant Secretary of State for Human Rights and Humanitarian Affairs and of human rights policy at the international financial institutions are followed by reviews of U.S. human rights policy toward Argentina, El Salvador, Nicaragua, South Africa, and the Soviet Union.
