The Construction And Use Of The Barrett Camera, Theresa Pauline Radermacher May 1947

The Construction And Use Of The Barrett Camera, Theresa Pauline Radermacher

Bachelors’ Theses

The study of the crystal structure of metals under various conditions of strain is at the present time the object of a great deal of scientific endeavor. A greater knowledge of the condition of strained crystals will be a tremendous aid in the future development of metallic construction for one can then predict the effect of any type of strain on a metal by the reaction of the individual crystals to that particular strain. It is the purpose of this paper to describe the construction and use of the Barrett camera which is used in experiments of this kind.

It was recognized rather early in the study of the phenomena of discharge of electricity through gases that the ordinary laws of conduction as found in solid and liquid conductors are not applicable to gases. It was shown by Zeleny and independently by Child that Ohm's law by no means represents the distribution of potential between electrodes in an ionized gas, but that the potential gradient is large in the vicinity of the electrodes, and not uniform throughout the space between them. When the pressure of the gas surrounding the electrodes is reduced to one or two millimeters and a …
