Methyl Methacrylate Casting Resin

Description: Abstract: "This report describes work done to improve the casting characteristics of methyl methacrylete resin under CMR-6-18 authorization. The experimental program was initiated with the objectives of decreasing casting time, bubble formation and shrinkage. It has been found that by use of a common solvent for monomer and polymer concentration in monomer can be attained greater than any previously reported in preparation of a methacrylate casting resign. Incorporation of this greater amount of polymer has produced the desired effects. A bibliography of relevant literature is included to which reference is made in the text."

The Boron-Carbon System: Quarterly Report No. 2, August 1, 1960 - October 31, 1960

Description: Abstract: A definitive investigation of the boron-carbon equilibrium system is being made by X-ray diffraction, metallographic, and thermal analytical techniques. Additional baron-carbon alloys have been prepared by sintering and arc-melting compacts prepared from boron and high-purity graphite. Metallographic examinations of these alloys are in agreement with alloys previously preapred from lampblack. X-ray investigation of sintered compacts indicates that the solubility range of boron carbide extends almost to pure boron. Boron of various purities has been annealed for times up to four hours, but no structure other than beta-rhombohedral has been detected. Very high purity boron (10 ppm impurity) has been obtained for the study of allotropy and the equilibrium relationships at very dilute carbon contents.

A Proposed Particle Containment Device

Description: Abstract: A device is proposed for confining charged particles to a localized region of space by means of the alternating electric field of a resonant cavity. The motion of single electrons in the field is stable. The limitations to particle density and temperature are discussed, and found to be too severe to allow the device to serve as a reactor, although it might be a useful laboratory tool.

The General Picture of Irradiation Damage to Tissues

Description: The following report is divided into two parts, both parts center around the effects of radiation on skin tissue. Part one focuses on superficial radiation, or Beta rays, while part two is on penetrating radiation, or neutrons and gamma rays.

Test of Water Quality by Impingement

Description: Report discussing an impinging experiment "to test the pitting tendencies of different qualities of water," specifically, alum coagulated water without sodium dichromate, alum coagulated water plus 2 ppm sodium dichromate, and ferrifloc coagulated water without sodium dichromate.

Beta Magnet Current Stability

Description: Abstract: A TEC regulator amplifier driving an Eaterline-Angus recording meter was used to record magnet current variations. Tests were made to determine magnet current variations. Tests were made to determine magnet current stability for currents from 500 amperes to 4000 amperes. Changes were necessary in both the TEC and GE regulators before currents below 2500 amperes could be regulated. Regulation to 0.025 percent for and hour was obtained for currents of 1000 to 4000 amperes with the TEC and GE regulators, and regulation to 0.05 percent for 500 ampere currents.

Consolidation and shaping of boron ; summary of previous work

Description: From abstract: "The deposit on the rods is in the form of a brittle uneven tube which is cracked off and subsequently pulverized to a 200-mesh powder. This report is chiefly concerned with methods of consolidating this powder and shaping it into forms required, though it also discusses to some extent other methods of shaping boron or born-rich materials."

The Metal-Dielectric Junction of High-Voltage Insulators in Vacuum and Magnetic Field

Description: From introduction: "This study is concerned with the shape of the electrodes of high-voltage insulator and with the method of joining them to the dielectric. The study is limited to insulators operating in vacuum, with special interest in the cases where strong magnetic fields are present. It is further limited to insulators with the high-voltage electrodes maintained at negative potential. The object of the study was to obtain information that would aid in improving the design of the insulators in two respects. First, to decrease to a minimum the number of charged particles set free which may directly or indirectly cause early failure of the insulator. Second, to increase the voltages at which partial or complete flashovers occur. Therefore, experiments were made to determine the principal phenomenon which have as their primary source the insulator under high electrical stress in vacuum."
