Performance of the upgraded small angle tile calorimeter at LEP

The small angle tile calorimeter (STIC) provides calorimetric coverage in the very forward region of the DELPHI experiment at the CERN LEP collider. The structure of the calorimeters, built with so-called "shashlik" technique, allows the insertion of tracking detectors within the sampling structure, in order to make it possible to determine the direction of the showering particle. Presented here are some results demonstrating the performance of the calorimeter and of these tracking detectors at LEP.
