Abstract
Results from an extensive study of nonprojective Shashlik calorimeter prototypes are reported. Nine (47 x 47 mm2) towers were exposed to a h igh energy electron beam at CERN SPS and read out by silicon photodiod es followed by low noise preamplifiers. The main results are the measu rements of the energy and shower position resolution and the angular r esolution of the electron shower direction. The shower direction measu rement is encouraging being in agreement at the tower center with a re solution of sigma(theta)(mrad) = 70/square-root E (10 mrad for 50 GeV electrons). The uniformity of the calorimeter response is found to be better than +/- 1%. The mean light yield measured in Shashlik towers e quipped with Kuraray Y7 WLS fibers and aluminized at the front end of the tower is of the order of 13 photons/MeV.
