Some commonly used formulas and principal data on the passage of fast charged particles through matter are presented. The areas covered include: atomic collision cross sections; stopping power for heavy charged particles; range-energy relations; shell corrections and I-values; straggling of heavy particles; coulomb and multiple scattering, and nuclear interactions; electrons; and mean energy for the formation of an ion pair.

General expressions are given for the field and its expansion coefficients produced by a two dimensional conductor structure surrounded by iron with a circular inside boundary. Saturation effects are described in terms of the tangential field at that boundary. The effects of the following types of perturbations are discussed: displacement, rotation and error excitation of a conductor, change of conductor shape, and modification of the inside contour of the iron. A design criterion is given to minimize the error fields associated with a displacement of the iron shell relative to the conductor structure. Expressions for the force and torque acting on a conductor are derived both for the unperturbed and perturbed magnet. Formulae are presented that allow convenient and fast evaluation of pertinent quantities with a computer when the structure is too complicated for hand computations.

This report is a summation on the history of the Freedom of Information Act, and contains a bibliography on the subject.

This report examines the issues involved in the Congressional consideration of pending legislation to authorize and fund the first phase of the SAFEGUARD anti-ballistic missile system. It provides an overview of the development of the system, provides estimated costs, and analyzes the threat of nuclear attacks against the United States.

Progress is updated for projects related mostly to biological and ecological radiation effects.

The purpose of this study can be divided into the three following parts: 1) to present complete sets of data obtained for projectile penetration into soil targets of precisely known properties, and to describe how to build and test these targets; 2) to present a numerical method of data analysis for empirically determining the force on a projectile, during penetration; and 3) to demonstrate how physical soil parameters, as well as impact velocity and a projectile property influence penetration.
