Determination of photon coordinates in a hodoscope cherenkov spectrometer

Abstract The characteristics of a hodoscope (cell-type) Cherenkov spectrometer made of TF-1 lead glass have been studied in a 25 GeV electron beam. It is shown that with cell dimensions of about 3.5 cm one can achieve an accuracy of about 1.5 mm in measuring the coordinates of high energy photons. The experiments are a continuation of analogous investigations performed earlier with a spectrometer made of TF-5 lead glass.
