Preliminary Investigation of a Five-Crystal Scintillation Gamma-Ray Spectrometer

Description: Abstract: A five-crystal scintillation gamma-ray spectrometer was constructed for use as a Compton coincidence spectrometer or as a pair coincidence spectrometer. Preliminary tests are discussed. The efficiency in either mode of operation was found to be low; however, the backgrounds were favorable and good definition of characteristic lines was achieved...Future tests and plans for improvements are discussed."

The Rolling of Gold Sheet for LAPRE 2 Pressure Liner

Description: From abstract: "This report discusses a special handling procedure devised to prevent contamination of high-purity gold while processing the metal from cast billet to final sheet. Gold of 99.99% purity was cast into rectangular billets and rolled into sheet whose final dimensions were 48 by 12-1/2 by 0.015 inch...As a final step, the sheet was annealed dead-soft in preparation for subsequent forming operations."

On the Possibility of Extracting Energy from Gravitational Systems by Navigating Space Vehicles

Description: This report describes a number of problems, generally involving the possibility of using reserved kinetic energy in such a way as to acquire, by suitable near collisions with one or the other of the celestial bodies discussed, much more kinetic energy that it possesses -- more by an order of magnitude than the available reserve energy would allow it to acquire by itself.

Pressure Balance in a Toroidal Pinch

Description: Abstract: In the study of a linear pinch, use of the equation of pressure balance has proven to be a powerful method of analyzing data taken with a magnetic probe. The toroidal pinch, however, is a geometrically more complicated object, and the use of the pressure balance equations is not so clean cut. It is the object of this note to analyze the pressure balance equations for a torus to the point where they might prove useful in interpreting probe data.

Design and Feasibility Study of a Pebble Bed Reactor-Steam Power Plant

Description: Originally issued as S and P 1963A, Parts I and II. This report covers a design and feasibility study of a pebble bed reactor-steam power plant of 125 megawatt electrical output. The reactor design which evolved from this study is a two-region thermal breeder, operating on the uranium-thorium cycle, in which all core structural materials are graphite. Fuel is in the form of unclad spherical elements of graphite, containing fissile and fertile material. The primary loop consists of the reactor … more
