Precise Vapor Pressure Measurement At High Temperature
"An apparatus using a silica Bourdon gage is described for the measurement of vapor pressures or dissociation pressures with an accuracy of 0.1 mm and 0.1 deg C up to maximum pressures of atmospheric or beyond and maximum temperatures of 650 to 1250 deg C. The method is applicable to corrosive substances, to substances whose vapor pressure is sensitive to slight changes in composition, and to substances difficult to purify of volatile contaminants which affect the vapor pressure."

Transient Beam Loading In Linear Electron Accelerators
"The subject of beam loading in linear electron accelerators has been discussed. With suitable design it is possible to place the equilibrium electron phase angle well ahead of the crest of the traveling wave in the accelerator. With beam loading the equilibrium position will move toward the crest, but the electron energy will remain constant or nearly so over a considerable range of loading. Some loss in energy will result from moving the equilibrium phase angle off the wave crest but the spread in energies due to beam loading should be reduced.

Radiation Damage to Vacuum Chamber Walls
"The problem of radiation derange to the walls of two types of vacuum chamber for the 6 Bev Cambridge Electron Accelerator was studied. Radiation damage may arise from the synchrotron radiation and from electrons which are not accepted at injection. The synchrotron radiation produces a large amount of secondary x radiation which is isotropic, and therefore complicates the arrangement of internal shielding. The 20 Mev electrons from the lines cannot be attenuated by shielding. It is concluded that dosages of the order of 10/sup 7/ rad/day near the inflector are unavoidable. This would exceed the allowable dosage for a tube made by cementing a stainless steel liner to supporting ribs, and also exceed the test dosages (so far as we know) for alumina ceramics."

Dynamic B and n-Behavior Up to 7600 Gauss in Magnet Model Mark Ii Comparison of Results With Long and Small Grad Coils
"Magnetic measurements were performance at excitation levels ranging from 4000 to 7600 gauss, to study the dynamic behavior of the magnetic and gradient lengths of the CEA magnet sectors. The influence of the proposed metal vacuum chamber on field and gradient was experimentally determined. Results of measurements made with a 26 in. long grad coil and with small circular grad coils are compared. The reliability of the 26 in. long grad coil is demonstrated."

Injection Trajectories and Beam Matching for the Cambridge Electron Accelerator
"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 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."

A Report on the Kinematics of High Energy Electron Scattering
"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."

Effect of Quadrupole Lenses
"The effect of correcting quadrupole lenses on the betatron oscillation characteristics of an AG synchrotron was studied, and general formulas are given for the fractional changes of the amplitude and phase functions. 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. "

Pole-Face Windings
"A summary is presented of a preliminary study of the application of pole- face windings to the Cambridge Electron Accelerator. Estimates are made of the currents required, the forces on the wibdings and the voltages induced by the magnetic flux. The possibility of automatic control of the pole-face currents in explored, and feasible control systems are suggested."

Betatron Oscillation Frequency Shift Due To "N-Errors"
