Results of Beam Inflection Tests

Description: "An experimental study has been made regarding the passage of a beam of 100-kV ions (H⁺ and H₂⁺) across a magnetic field by means of a crossed electric field." This experiment was designed to answer the following questions: "(1) Is there a limit to the current that will traverse a magnetic field by the action of a crossed electric field? If so, what is the limit? (2) Do difficulties arise in maintaining the electric field? (3) For the source employed, what is the angular divergence and current … more

Reactions of the Refractory Silicides With Carbon and With Nitrogen

Description: Abstract: The silicides of Ti, Zr, Ce and Nb were investigated to determine the phases present at temperatures around 2000 K. The reactions of silicides of Ti, Zr, Ce, Nb, Ta, Mo, and W with carbon were studied at these temperatures. Also a limited amount of work was done on the reactions of some of the silicides with nitrogen. The data have been used to establish ternary phase diagrams for the systems and to obtain upper and lower limits for the heats of formation of the silicides.

The Scattering of 10-Mev Protons on Carbon and Magnesium

Description: From Abstract: "In order to study the mechanism of excitation of nuclear levels by inelastic scattering, a scattering chamber of 36-inch diameter was constructed. The deflected beam of the Berkeley 60-inch cyclotron was brought out of the shielding by means of strong focusing magnets. Particles from the nuclear reactions were detected by either of two systems, a quadruple proportional-counter telescope, or a coincidence crystal spectrometer. Energy resolution was of the order of 2.5%."

Pyrotron High-Energy Experiments

Description: "In these studies ions of several-kilovolts energy were extracted from an ion source located inside one of the peaks of the mirror field...The extraction slot of the source is located near the field injection plane, about midway between the mirror peak and the center, and ions are injected perpendicularly to magnetic field lines. In their traversal of the distance between the mirrors, the ions are in an inhomogeneous magnetic field and have a component of velocity along curved field lines. This… more
