In connection with other research work in the physics department at the University of New Mexico it became of interest to make a detailed study of a resistance-capacitance couples low-pass filter which incorporate inverse feed-back. In order to determine the effect of the inverse feed-back on the filters, calculations are made on circuits with and without feed-back. Response curves are calculated for step-wave inputs and for sine-wave inputs, and these calculated curves then compared with experimental response curves.

In general there exist in the energy level scheme of many of the elements, transitions which give rise to the liberation of energy in the visible or near visible spectra. This situation gave rise to the hope that a gaseous element could be selected such that upon being excited or ionized by charged particle radiation, the predominant transitions to lower energy levels could be detected by photographic means. If a means of detecting these transitions could be made sufficiently sensitive, one could then hope to detect very low radiation intensities of charged particles. The problem consisted of evacuating a chamber, …
