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 pulsed electric quadrupole lens in the synchrotron in combination with two deflectors between linac and synchrotron can be used to place particles of different energies on their specific equilibrium orbits. A layout of the whole injection system following the output of the linac is given."</p>A Report on the Kinematics of High Energy Electron Scattering2023-11-05T07:39:13-06:00https://digital.library.unt.edu/ark:/67531/metadc1202052/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1202052/"><img alt="A Report on the Kinematics of High Energy Electron Scattering" title="A Report on the Kinematics of High Energy Electron Scattering" src="https://digital.library.unt.edu/ark:/67531/metadc1202052/small/"/></a></p><p>"A convenient summary is given of useful formulas on the kinematics of high energy electron scattering together with a derivation of the relevant formulas for transforming from the center of mass to the laboratory system such parameters as scattering cross sections. The formulas derived hold for any two- body collision: the approximation (m = 0) employed for the electron scattering calculations is rigorously true for the elastic scattering of photons."</p>Amplitude and Phase Functions for the Revised Parameters of the Cambridge Electron Accelerator2023-11-05T07:39:13-06:00https://digital.library.unt.edu/ark:/67531/metadc1202053/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1202053/"><img alt="Amplitude and Phase Functions for the Revised Parameters of the Cambridge Electron Accelerator" title="Amplitude and Phase Functions for the Revised Parameters of the Cambridge Electron Accelerator" src="https://digital.library.unt.edu/ark:/67531/metadc1202053/small/"/></a></p><p>"The phase and amplitude functions describing the betatron oscillations in the synchrotron are calculated using the revised parameters of the Cambridge Electron Accelerator.

Calculations performed for different setups of different numbers of lenses for the CEA synchrotron structure point out that one may correct for sizable errors in the n- value by means of 8 pairs of quadrupole lenses in two consecutive straight sections with the focusing lens between defocusing sectors and vice versa. An increase of BETA /sub max/ of about 5% is obtained for DELTA n/n approximately 0.04. It was found that the necessary corrections can probably be obtained satisfactorily with lenses of 6 in. length.

From the lubrication equations an inequality is obtained for the internal film temperature rise, after which the isothermal film equations are derived. Then, for perfectly-aligned self-acting journal bearings, a conservation equation is obtained. For gas bearings this condition gives: [formula] constant along the axis of the bearing. Application of this condition to the infinitely-long gas bearing gives more accurate pressure solutions for this case. The Katto-Soda form of the differential equation for the infinitely-long bearing is solved by a series expansion in the eccentricity ratio, the first terms of which give the original, approximate Katto-Soda solution. In addition, solutions obtained numerically by digital computations are presented in graphical and tabular form for eccentricity ratios from 0 to 0.9 and compressible bearing parameter [formula]. Design charts based on these calculations are provided.</p>Time Variation of Thermodynamic Parameters of a Gas in the Region of a Shock Front : Progress Report III2023-07-09T18:09:52-05:00https://digital.library.unt.edu/ark:/67531/metadc1248802/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1248802/"><img alt="Time Variation of Thermodynamic Parameters of a Gas in the Region of a Shock Front : Progress Report III" title="Time Variation of Thermodynamic Parameters of a Gas in the Region of a Shock Front : Progress Report III" src="https://digital.library.unt.edu/ark:/67531/metadc1248802/small/"/></a></p><p>The original goal of this investigation was to compare the thermodynamic characteristics of the gases in and behind the shock fronts in gases at initial pressures in the millimeter range and to compare these characteristics in the geometries of single and double discharges. The shock fronts were not visible, so it was not possible, at these pressures, to get visual data from the shock front itself. The parameters giving the properties of the gases were faces. Measurements made with an image converter camera (which is still in the development stage) agree well with these made with a photomultiplier tube. Differences are observed between the front velocities in the cases studied. These are of the order of 3 to 15 per cent. Considering the nature of the shot to shot fluctuations in the discharges and the inductance variation between the single and double discharges represent a physical difference. The mathematical treatment which says that two equal strength colliding with a wall behaves, has not been shown to be inadequate by this investigation. It was hoped that a stronger confirmation could be fien to the theory, but the accuracy of the data does not warrant it.</p>The SNAP II Power Conversion System. Topical Report No. 3.

The return to an equilibrium structure during annealing was observed by means of mechanical tests and etching techniques. Crystals containing three levels of impurity, zone refined, commercially pure, and doped with 0.05 mole per cent magnesium, were used in order to separate the effects of foreign ions from those of thermal vacancies. The changes of mechanical properties produced by quenching and by subsequent annealing were generally attributable to point defect-dislocation interactions. Precision density determinations indicated that about 10% of the equilibrium concentration of vacancies at the melting point was retained at room temperature by the quench. The density could be restored to its normal value by annealing. Two important annealing stages were observed. At about 200 deg C the precipitation of impurities retained in solution by the quench caused a sharp increase in the hardness as measured at room temperature. Isothermal annealing revealed the hardening process to have an activation energy of about 0.5 ev which is probably the energy for migration of an associated magnesium ion-lithium vacancy pair. Between 300 and 400 deg C the removal of dislocations and probably vacancy clusters resulting from the quench caused pronounced softening so that the quenched-annealed crystals were softer than as-grown-annealed crystals.

The result is then specialized to the beta - gamma correlation and applied to two cases in which additional properties of the photon are specified, the circular polarization and the plane polarization. The prospect of testing time reversal and determining nuclear matrix element ratios by beta - gamma correlation measurements is explored using the nuclide Tm/sup 170/ as an example. The directional angular correlation between the 2.31-Mev beta and the subsequent 0.605-Mev gamma emitted in the decay of Sb/sup 124/ was measured as a function of the beta energy. The K-conversion coefficient of the 279-kev gamma following beta decay of Hg/sup 203/ was measured by comparing the x-ray and gamma intensities in a scintillation spectrometer. The measured valve of alpha /sub k/ = 0.195 plus or minus 0.014 indicates that the transition is M1 with E2 mixed to the extent of 63%.
