Particle Detector Development and Performance

Summary This paper describes a scintillation spectrometer, which measures the energy of the pairs produced by gamma-rays. Each gamma-energy gives a symmetric peak in the energy distribution. The width at half-maximum is 7% at 4 mev. The greatest advantage of this apparatus is the high sensitivity. It has been possible to measure sources with a strength of about 0·1 μc.
