Silicon detectors in electromagnetic and hadronic calorimetry

Abstract

A review of investigations performed by SICAPO collaboration at CERN and Si/W and Si/U sandwich calorimeters employing silicon detectors as active medium is presented. Experimental results, such as the response of sensed energy versus incoming electron energy and depleted layer width, of the longitudinal and lateral development of electromagnetic showers and of the energy resolution, are described. Mosaic modules of silicon detectors, which enable the construction of silicon sampling hadronic calorimeters, are also given. A comparison of results from SICAPO, Hamburg (Si/Pb) and from Tokyo (Si/Pb and Si/W) calorimeters is shown.
