e/x SEPARATION IN THE COF END PLUG EM AND HADRON CALORIMETERS

e/x separation was studied by applying a genaralized X2 method on 100 GeV eand xtest beam data of the CDF End Plug Calorimeters. x rejection power increases as the number of longitudinal segments of the EM calorimeterincreases with or without using the information of energy deposit in the backing Hadron Calorimeter. The r. m. s. of lateral distribution of enrgy deposits in the" and ep strips of the EM calorimeterare effective to reject x's.
