Characteristics And Calibration Of A Large Liquid Scintillator, James R. Barcus Jun 1959

Characteristics And Calibration Of A Large Liquid Scintillator, James R. Barcus

Physics & Astronomy ETDs

It is the purpose of this thesis to present in some detail the method and results of the calibration -- in particular, the determination of the single particle pulse height which is crucial to any meaningful interpretation of the observational data.


Recording Of Geomagnetic Field Variations In An Orthogonal System, Chistian Schroeder Jun 1959

Recording Of Geomagnetic Field Variations In An Orthogonal System, Chistian Schroeder

Physics & Astronomy ETDs

Magnetic field variations in both magnitude and direction are known to occur due to such phenomena as atmospheric tides and solar activity. Magnetic storms caused by solar activity may bring about variations in excess of one percent of the magnitude of the earth's normal magnetic field; but in general the changes are slight and require sensitive instruments for their measurement.


The Absolute Excitation Functions For The I 127 (N,Y) I 128 And Na 23 (N,Y) And Na 24 Reactions, Richard L. Cubitt May 1959

The Absolute Excitation Functions For The I 127 (N,Y) I 128 And Na 23 (N,Y) And Na 24 Reactions, Richard L. Cubitt

Physics & Astronomy ETDs

Radiative capture (n,y) cross sections, in addition to their theoretical interest, are of great practical importance to the technology of reactor design. A knowledge of the absolute excitation functions of the various materials employed in reactors permits calculation of the effect of these materials on the reactivity of a reactor, and also enables shielding calculations to be made.
