High energy electromagnetic shower position measurement by a fine grained scintillation hodoscope [electronic resource]
We have measured the centroids of high energy electromagnetic showers initiated by positrons in the energy range 2 to 17.5 GeV with a fine grained scintillation hodoscope composed of seven 1 cm wide elements placed behind a 3.6 radiation length (15 cm) converter composed of SCG1-C scintillation glas...

| Summary: | We have measured the centroids of high energy electromagnetic showers initiated by positrons in the energy range 2 to 17.5 GeV with a fine grained scintillation hodoscope composed of seven 1 cm wide elements placed behind a 3.6 radiation length (15 cm) converter composed of SCG1-C scintillation glass. A simple first moment calculation using the ionization observed in each element of this hodoscope yields a shower position resolution as a function of energy of: sigma (mm) approx. = 0.7 +- 5.6/..sqrt..E(GeV). We present results on the energy dependence of the shower profiles and the ionization measured by this hodoscope. |
