Popis: | A prototype module for the electromagnetic shower calorimeter has been constructed and its characteristics have been measured. It consists of 38 layers of planar proportional chambers interleaved with 3 mm thick lead plates. The proportional chamber is made of conductive plastic tubes as a dc cathode and pickup electrodes as an rf cathode. The pickup electrodes are copper-clad G-10 panels etched with finely segmented patterns which, when assembled, form complete conical towers. The module was tested using high energy electron and hadron beams of energy range from 25 GeV to 150 GeV. Energy resolution is 24% E( GeV ) , and the position resolution is 1.5 mm or better at and above 50 GeV. The lateral and longitudinal distributions of the energy deposit are studied and they are applied to π e discrimination. |
