Abstract
We have measured performance of a lead/plastic scintillator sampling calorimeter in two separate beam tests at low (1-4 GeV) and high (10-200 GeV) energies. The calorimeter is composed of 8-mm-thick lead plates and 2-mm-thick plastic scintillator plates for hardware compensation, where responses to electromagnetic and hadronic showers of the same energy are identical. We find the linearity to be better than 1% in the energy range between 2 and 150 GeV for both pions and electrons. The energy resolutions are obtained to be (46.7 ± 0.6)%/√E ⊕ (0.9 ± 0.9)% for pions, where the energy E is given in GeV. The response ratio of electromagnetic showers to hadronic showers is measured to be 1.04 ± 0.01 at low energies, and 0.99 ± 0.01 at high energies.
