A Scintillation Amplitude−Coordinate Spectrometer

The scintillation amplitude−coordinate spectrometer with a thickness of 0.58 X 0 has been calibrated using cosmic radiation. The light signals in the spectrometer are detected by FEU-49 and FEU-85 photomultiplier tubes, which determine the amplitude and coordinate systems, respectively. It has been established that the relative amplitude and coordinate resolutions depend on the point of particle incidence on the spectrometer. The relative amplitude and coordinate resolutions measured at the center of the spectrometer appear to be the best, and their values are ~8.7% and ~1.6 cm, respectively.
