Completion of the L3 e.m. calorimeter with a lead-scintillating fibers spaghetti calorimeter

We report on the test-beam results for three prototype modules of a lead-scintillating fiber ( spaghetti ) calorimeter. We studied linearity, energy resolution and light collection. The results are in agreement with expectations from MC simulation. We also report on the studies for the optimal light guide to be used in the final design.
