Electrostatic Classification of Submicron Airborne Particles : Final Report, August 16, 1961 to January 31, 1963

Description: From abstract: "This project was a study of electrostatic classification of submicron aerosols. Classification of particles as small as 0.006-[mu]-diameter was shown to be feasible, and good classification of atmospheric dust was achieved. However, a practical solution to the problem of overlapping between particles larger and smaller than 0.1 [mu], the point of minimum electric mobility, was not found."

Penetration Effects in Magnetic-Dipole L-shell Internal Conversion

Description: Internal-conversion coefficients may be thought of as consisting of two parts: a usually dominant part which depends only on the atomic number and the nuclear transition energy, and a usually small part depending explicitly on nuclear transition matrix elements. This latter part arises from the penetration of the converting atomic electrons within the transforming nucleus.

A Simple Theory of the Process P+P → D+W+

Description: The discovery of the vector meson which mediates the weak interactions, W,1 would be of extreme importance for weak interaction physics and for field theory in general. The W, if it exists, will be made in a variety of processes such as v+N →W+ + e- + N, or n- + P →W- + P, or, as studied in this note, P + P → D + W+. The W couples to leptons with a dimensionless constant [constant not transcribed] where G is the Feral constant defined t=so that [constant not transcribed]. Thus for [equation not… more

Some Further Remarks on Beam Current Measurements in the AGS

Description: A previous report on this subject (Brookhaven National Laboratory, AGS Internal Report, ECR-4) described in detail the methods of measuring the injected and accelerated proton currents in the Brookhaven AGS up to May 1961. At that time the accelerated current was measured by extracting the bunch frequency component of the signal given by a pair of radial position observation electrodes. The injected current was also determined by the signal induced on a similar pair of radial position electrode… more

Beam Separators for Bev Particles

Description: The problem of separation of beams of particles of different masses but of the same momentum at Bev energies is the subject of a great deal of study at several high energy laboratories. In this note we shall describe the problem and tabulate a few of the cogent parameters. Frequently the student of high energy interactions is faced with a beam of miscellaneous particles coming from an accelerator. By standard techniques this beam can be rendered approximately parallel and an inch or so in diame… more

Production of Mg28 - State of the Art

Description: Sheline and Johnson made Mg28 through the reactions Si30(γ,2p)Mg28 and Mg26(α,2p)Mg28 in order to characterize and determine a decay scheme for the new nuclide. Lendner separated a magnesium fraction from the spallation products of the irradiation of chlorine, as sodium chloride, with 340-MeV protons. The 21-h activity that was present was deduced to be Mg28 from the 2.3-m half-life of the Al28 that was milked from it, as Sheline and Johnson had done.

Oak Ridge National Laboratory Target Preparation Program

Description: In early 1961 a Target Fabrication Center was established at Oak Ridge National Laboratory to carry out the routine preparation of a wide variety of targets and to provide research and development support to the target program. Although most of the effort concerned enriched stable isotopes, both normal and radioactive materials are also handled. With the aid of rolling mills, resistance-heat and electron-bombardment vacuum evaporation, presses, and electroplating equipment, targets of elements … more

The Uranium-Rhenium Alloy System

Description: Abstract The phase diagram of the uranium-rhenium alloy system is presented along with a discussion on transformation kinetics of the uranium solid solutions. The phase diagram is of the double eutectic type with the intermediate phase having the composition URe2. This phase exhibits allotropy at 180°C and melts congruently at 2200°C. URe2 reacts sluggishly with the uranium solid solutions below 750°C to form the peritectoid compound U2Re. Eutectic reactions occur at 1105° and 2105°C at respec… more

Stratospheric Monitoring Program

Description: "Design work was completed and construction initiated on a prototype field altimeter based on the gas density dependence of Townsend discharge current in an electrical discharge. The design of an ion tracer air velocity meter for laboratory applications, and construction of three units were successfully completed. Theoretical and experimental support is presented, showing the applicability of the ion tracer system to the accurate measurement of linear gas velocity. The operating range of the la… more

Measurement of the Rate for n" + He3 - H3 + [v]

Description: Measurement rate has been made using a high pressure, He3 filled, gas scintillation counter as the target for stopping muons. The counter is well suited to the problem since it allows for clean separation of the 1.9 MeV triton recoils and muon decay electrons, which are 300 times more numerous. The tritons, because of their short range, are detected with close to 100% efficiency, whereas the energy lost in the counter by the minimum ionizing electrons is less than 0.8 MeV in all cases. Furthe… more

On the Transfer of Heat to Fluids Flowing Through Pipes, Annuli, and Parallel Plates

Description: Nusselt numbers have been calculated for heat transfer to fluids flowing through annuli under conditions of uniform heat flux and fully established velocity and temperature profiles. The following cases were considered: (a) laminar flow, (b) slug flow, (c) turbulent flow with molecular conduction only, and (d) turbulent flow with both molecular and eddy conduction. These Nusselt numbers were determined for two conditions: heat transfer from the inner wall only and heat transfer from the outer w… more

Propagation Characteristics of Capillary Ripples, I. The Theory of Velocity Dispersion and Amplitude Attenuation of Plane Capillary Waves on Viscoelastic Films

Description: From abstract: "The boundary value problem for velocity of propagation and attenuation of capillary ripples over viscoelastic surface films is set up and solved from the viewpoint of continuum hydrodynamics. Both soluble and insoluble films are treated. Successive approximation methods are used to derive explicit formulae for velocity of propagation and amplitude attenuation; formulae for these quantities accurate to second order are given for slightly viscoelastic and highly viscoelastic films… more

Design of He3-Filled Fast Proportional Counters

Description: From American Physical Society 1963 Annual Meeting, New York, Jan. 1963. Electron drift velocity measurements have been made on helium, helium--CO/sub 2/, and helium--CH/sub 4/ mixtures in order to determine the optimum design parameters for He/sup 3/-filled proportional counters. It is shown that small (<1 in. dia) counters with neutron-detecting efficiencies of greater than 1% at 1 Kev and with jitter times of less than 1 mu sec are practical. Calculated and measured jitter times for several … more

Experimental Studies on the Current Carrying Capacity of NbZr Wires Under Conditions of Fixed and Swept Magnetic Field

Description: Abstract: The current-carrying capacity of Nb- Zr wire has been studied under conditions of swept magnetic field and fixed wire current and of fixed magnetic field and swept wire current. The effects of wire movement, thermal environment, copper coating of the wire, and rate of sweep of wire current or magnetic field have been determined for these conditions of test.

Experiments on a Large Volume Electron-Cyclotron Heated Plasma

Description: As part of the thermonuclear effort at Oak Ridge National Laboratory, large volume high-beta plasmas have recently been produced by microwave power at the electron-cyclotron frequency. The original work was done with 13-cm microwave radiation in a magnetic mirror and was reported at Salzburg. Since that time, higher frequency and higher power radiation has been used in a succession of experiments. The current experiments involve heating a plasma in the EPA Facility which has a 3:1 magnetic mirr… more
