The aim of this work is to show a calibration method of a test system that will be systematically implemented for the particle detectors devel- oped and produced at the ITeDA facilities. A big number of more than 16000 individual scintillator strips of 4.1 cm x 1.0 cm x 400 cm will have to be tested together with its associated optical ber. A reliable and fast testing method is therefore compulsory to characterize all the detectors. The detector testing routine consists of two steps: rst each scintillator is scanned using a 137Cs radioactive source to obtain its decay curve and, secondly, the resulting curve is normalized by means of background muons using a coincidence device through a specic point over the scintillator. The details of the calibration procedure are presented along with prelim- inary results from a prototype detector testing.
