Effect of an oriented crystalline converter on the electromagnetic spectrometer response

Abstract

The results of the experimental studies of the response of an electromagnetic spectrometer with a converter made of 〈111〉 tungsten crystal at electron energies of 26, 28, and 31 GeV are presented. It is found that the ratio of the difference between positions of the cascade curve maximum for misoriented and oriented converter to the difference between energy releases at the cascade curve maximumis a constant value at a given electron energy, converter type and thickness, and is independent of the converter temperature.
