We present the study of a lucite light guide system developed for the modules of the electromagnetic calorimeter that will be installed in CLAS at CEBAF to detect showering particles emitted at angles larger than 45°. We show that it is possible to produce lucite guides with length up to 120 cm and to adapt them to the module geometry with low costs, time and efforts. The performances are comparable or even better than that of equivalent systems realized with optic fibres. The guides showed high homogeneity and light transmission efficiency.

Abstract
We present the study of a lucite light guide system developed for the modules of the electromagnetic calorimeter that will be installed in CLAS at CEBAF to detect showering particles emitted at angles larger than 45°. We show that it is possible to produce lucite guides with length up to 120 cm and to adapt them to the module geometry with low costs, time and efforts. The performances are comparable or even better than that of equivalent systems realized with optic fibres. The guides showed high homogeneity and light transmission efficiency.
