"Tests have been made in the Langley 4- by 4-foot supersonic pressure tunnel at Mach numbers of 1.41, 1.61, and 2.01 of various arrangements of a 0.04956-scale model of the Convair F-102A airplane with faired inlets. Tests made of the model equipped with a plain wing, a wing with 6.4 percent conical camber, and a wing with 15 percent conical camber. Body modifications including an extended nose, a modified canopy, and extended afterbody fillets were evaluated" (p. 1).

Three methods are discussed for detecting ionizing radiation and transitting the intelligence. All three methods make use of the reactamce variation of a frequency determining network, to vary the frequency of an R.F. transitter as a function of ionizing radiation entering an ion chamber or counter. The first method is based on the capacitance znd subsequent frequency variation of am electrometer incorporated in an ion chamber. The variation is achieved by a moving came electrometer, where the position of the vane changes as a function of the leakage of an electrostatic charge when exposed to radiatioz and thus varies the electrometer capacitance. Gamma, beta particles, and fast neutrons were measured during these experiments. The second method replaces the moving vane electrometer by ferroelectric capacitances. This reduces the sensitiwity, but permits movement of the instrument during exposure. These ferroelectric capacitances are physically very small and can be enclosed inside of an ion chamber. The varintion of the capacitance with charge or voltage permits measurement of the ionination current as a function of capacitance and frequency. The third and most successful method replaces the ion chamber by a Geiger counter, single pulses and integrated pulse rates can be measured and transmitted. (auth)

Abstract: "A magnetohydrodynamic model of a plasma-magnetic field instability, using liquid sodium, has been observed. The growth rate and wave length of the Taylor-type acceleration instability was observed to be in agreement with the theory of Kruskal and Schwarzschild."

Information concerning the transformation kinetics of the gamma solid solution of uranium-base alloys is important. Accordingly, the metastability of the gamma phase was investigated for nine uranium-rich alloys of the U-Mo-Pt, U-Mo-Nb, and U-Nb systems. Samples were encapsulated in Vycor bulbs, solutions treated at 1000 decrees or 1050 degrees C, quenched to and annealed at temperatures between 600 degrees and 300 degrees C. Techniques employed to follow transformation included metallography, resistivity, X-ray diffraction and hardness. A difference exists between the TTT curves for the same alloy determined by different techniques. However, this is readily explained. The body-centered cubic gamma phase of the U-Mo and U-Mo-X alloys decomposes eutectoidally to form alpha and epsilon, an ordered structure. The eutectoid temperate is about 575 degrees C in the binary system. In the U-Nb system the gamma solid solution decomposes monometrically (or eutectoidally) to a product of alpha and another niobium-rich gamma phase. Alpha uranium has characteristic low solubility for either of the alloy components. The nose of the TTT curves for the U-5.1 wt % Mo and U-10 wt % Nb compositions exists at about 550 degrees C and 0.1 hour. Minimum times for transformation are longer for the other alloys. Rather …

Introduction: This note describes briefly the current concept of the experimental program on source development for mirror machines. There are two major facilities involved: (1) A comparatively small machine whose code name is "Guppy", and, (2) A larger d.c. mirror geometry whose code name is "Waldo."

Report discussing high-speed cascade tests made of a blade section designed for conditions typical of the hub section of high-flow transonic rotors. The intent of the testing is to provide information on the effects of local surface Mach numbers on blade performance. The test results, effect of more forward location on peak surface velocities, effect of increase in pressure-rise coefficient, effect of Mach number and pressure rise on turning angle, and a comparison of variation in momentum-loss coefficient with surface pressure-rise coefficient are provided.

Two-group constants have been prepared for a range of steel-water volume ratios. A calculation of critical mass and flux distribution has been made for an existing steelwater critical experiment. In order to check the experimental critical mass the age was increased. The effect of this adjustnnent on flux distribution was noted. The critical mass and flux distribution were calculated for the clean APPR critical experiment using the adjusted curve of age vs steel- water volume ratio. The calculated critical mass of the clean APPR critical experiment was 9.04 kg of U/sup 235/. (auth)
