On The Relation Between The Cosmic Ray Air Shower Spectrum And The Pulse Height Spectrum Of A Large Scintillator, Robert T. Barton Jun 1958

On The Relation Between The Cosmic Ray Air Shower Spectrum And The Pulse Height Spectrum Of A Large Scintillator, Robert T. Barton

Physics & Astronomy ETDs

The purpose of this paper is to study other lateral distribution functions proposed by various authors, to select an alternative to the one used previously, to repeat the calculations of the required quantities using the alternative function, and to comment on the relative merits of the different choices. Since an empirical formula was used in the original work it seemed desirable to use a theoretical relation for comparison if a suitable one were available.


A Problem In Atmospheric Diffusion, Albert C. Giere Jun 1958

A Problem In Atmospheric Diffusion, Albert C. Giere

Physics & Astronomy ETDs

This study concerns the diffusion of atmospheric ozone through a one dimensional region, given certain initial and boundary conditions. As shown in Figure 1 the region is bounded by the planes x= -a and x=b. The plane x=0 divides the region into two parts, Region I and Region II. The solution to this type of problem consists in giving the concentration as a function of the time for any point x in both regions. A general analytic solution is obtained by means of the Laplace transformation using coefficients of diffusion which differ in Regions I and II, but which are …

A Rotating Ring Magnetometer Remote Position Indicator, Robert B. Foster Jr.

Physics & Astronomy ETDs

Many phases of present-day experimental physics require remote indicating devices where data must be transmitted either by wire or radio to a distant point. For example, when atmospheric parameters are measured by means of sounding balloons, it would be desirable to use a lightweight device which would accurately convert measured information into electrical data in a form which would allow easy transmission to a receiving station.
