Abstract :
A prototype of an electromagnetic sampling calorimeter for future linear collider experiments has been commissioned by the LCCAL collaboration. In order to improve the reconstruction of the shower profile, three silicon pad detector planes have been inserted between lead and scintillator layers at 2, 6 and 12 X0. The scintillator light is collected by means of lateral W.L.S. fibers. The electrical parameters of the pad detectors have been determined by a static IV and CV characterisation; charge collection efficiency and tracking capability have been measured during beam tests. Results from test-beam runs are shown.
