ELECTROMAGNETIC SHOWER ENERGY FILTERING EFFECT - A WAY TO ACHIEVE THE COMPENSATION CONDITION (E/PI=1) IN HADRONIC CALORIMETRY

Equalization between the electromagnetic and the hadronic signals is the condition for obtaining the linear response of a calorimeter to hadronic showers and an energy resolution that improves as the incident energy increases. In a calorimeter with silicon readout, the use of a combination of low-Z and high-Z materials as absorbers allows the transformation of the electron energy distribution of the incident showers in two media with different critical energies. As a result, the response of the calorimeter to incoming showers is modified to achieve the compensation condition (e/pi=1)
