Improvement of an Energy Spectrum by Means of a Timing Technique

Abstract The constant fraction (CF) discrimination technique was applied to gamma rays emitted from a gamma source via a developed spectrometer. Experimental energy spectra, with and without the CF discrimination technique, were obtained separately. After the application of the technique, the spurious radiations on the low energy tail of the energy spectrum which had arisen from the low‐energy background, backscattering and Compton radiations were partly discriminated, leading to improvement in the energy spectrum.
