Energy Measurements With Proportional Counters

Design of a proportional counter and its application to Tb156 radiation

“…Thus one might suspect that vq < m^. Confirming this suspicion, West (10) displays experimental data in agreement with Fano's calculation (31) that vq should lie in the range m^/2 > vq > m^/3.…”

“…Although used for many years as radiation detectors (1,2,3,4,5), the full extent of their usefulness, particularly in the low energy region, was first indicated by Kirkwood et al (6) and Curran et al (7) less than ten years ago. Since then, considerable effort has been ex pended (8,9,10,11) along experimental lines dictated by the following unique characteristics of proportional counter spectrometers: a. Adaptability to the use of gaseous sources for the study of soft electrons. b.…”

Design of a proportional counter and its application to Tb156 radiation

“…The phenomena involved in the multiplication process have been des cribed in detail in the literature (2,3,6,5,9,10), but several features of the theory deserve particular attention in view of the effort here to achieve high resolution, the contemplated use of this counter in coin cidence experiments and the desire to make available data which may aid in the future design and operation of similar instruments.…”
