Evaluation of Seal Weld Joint Designs

Description: Report discussing a program to investigate the properties of two types of seal welds for Synthetic Aperture Radar (SAR) components. The objective of the study is to determine mechanical properties of concave canopy seal welds and convex canopy seal welds, determine if these two seal weld joint designs can be used safely for fabrication of SAR components, and to develop optimum welding conditions and weld joint designs for uniform full weld penetration using a concave and a convex canopy weld.

Isotopic Sources of Secondary Radiation : Interim Technical Report Covering the Period from June 15, 1958 to March 1, 1959

Description: During the first eight months of this program the emphasis has been places on experiments and calculations on the x-ray target configurations and materials. We have found, by extending the experimental information using Pm147, Kr85, and Sr90-Y90, as well as by developing the theoretical x-ray production for these sources, the approximate conditions under which isotopic sources will emit nearly monochromatic x-rays suitable for gaging and radiographic application in the 10 to 100 Kev photon ener… more

Results of Parallel Flow Oscillator Studies. Progress Report No. 2

Description: From the results of the tests it is clear that changing from series to parallel flow effects little or no change i the nature of the reactivity feedback. The physical processes which characterize the magnitude and time dependence of the negative power coefficient of reactivity are apparently identical in both instances. Accordingly, it is reasonable to infer that the conclusions reached as he result of the series flow studies are still valid. These are :(1) the overall power (temperature) coeff… more

Injection Trajectories and Beam Matching for the Cambridge Electron Accelerator

Description: "ABS>Injection trajectories were calculated for different injection conditions for the Cambridge Electron Accelerator, considering also the effect of magnetic fringing fields. The general problem of matching the emittance of the linac to the acceptance of the synchrotron in the transversal phase space is considered, and it is shown that this can be done by a set of two quadrupole lenses. In order to eliminate rudial betatron oscillations due to energy deviations of the injected particles, a pul… more

Precision Beta-Ray Spectroscopy : Termination Report

Description: Detailed information on the radiations associated with several even-even isotopes has been obtained. In some instances enough information has been gathered to allow construction of skeleton energy level diagrams for the isotopes. Activities studied were obtained from pile irradiation of pure odd-even natural isotopes and included Dy160, W182, Sm152, Gd152 and Gd154. Details of the work done on and results obtained for these isotopes are reported in section 3. Some analytic and experimental stud… more

A Pulser Circuit for Magnetizing Ferro-Magnetic Devices

Description: This paper describes a single-pulse, high-current pulser used to magnetize ferromagnetic cores. The circuit is an R, L., C combination designed to eliminate any spurious ringing. This makes it possible to obtain accurate waveforms of the current and voltage applied to the cores. From these waveforms, the magnetizing force applied to the cores and the flux change in the cores can be accurately determined. Also discussed are some special problems which were encountered when attempting to magnetiz… more

Some Measurements of Acceleration Produced by Sound Pressures

Description: This paper contains the results of an experiment performed to determine the effects of sound pressure on acceleration of a test specimen. Particular attention is given to determining the resonant frequency and amplitude of acceleration of the test specimen as a function of mass, sound pressure and frequency.

Viscosity Studies on the Sodium Deoxyribonucleates Obtained from Pneumococcus Type III and Pneumococcus Type VI

Description: In order to gain more information about the molecular characteristics of the sodium deoxyribonucleates isolated from pneumococcus type III and pneumococcus type IV, a series of viscosity studies was undertaken on each of these deoxyribonucleates. The method employed to estimate the molecular weight of thymus sodium deoxyribonucleate was employed here to estimate the molecular weights of the deoxyribonucleates from type III and type VI.

The Proton-Proton Triple Scattering Parameters R and A at 213 Mev

Description: "As a part of a program to determine the p-p scattering matrix at 213 Mev, the triple scattering parameters R and A were measured at 30, 40, 50, 60, 70, 80. and 90 deg in the center-of-msss system. The results are compared with a phase shift analysis by MacGregor and Moravcsik and with the predictions of the boundary condition model of Saylor, Bryan and Marshak."

Comparison of Radiation-Induced Graft Copolymerization Untilizing Electron Accelerators and Isotope Sources as Radiation Initiators

Description: "A brief examination of the post irradiation grafting of machine irradiated polyethylene film with acrylic acid monomer was made. Evidence of postgrafting was detected in samples that had been irradiated to a total dose of 10 Mrads at a dose rate of 0.01 Mrad/sec. and then exposed to a 25% purified acrylic acid solution in benzene for periods of 1 to 4 days."

Preliminary Studies for the Separation of HD from H2 by Rectified Absorption

Description: The feasibility of rectified absorption for the recovery and purification of HD from H2 streams has been investigated. The absorbent considered was liquid nitrogen at 78 (degrees) K. The process appears to present no major engineering or operation problems. Cost calculations indicate that the process may be economically competitive with other processes. Process design was based on an estimated separation factor of 1.25 between H2 and HD in this system. Experimental work has been undertaken… more
