Abstract
We have tested new scintillator modules with silicon photodiode readou t for the upgraded Active Lead Rings (ALR) of the L3 detector at LEP I I. Results are presented from data recorded in muon and electron test beams with particular emphasis on the light production and collection as a function of the particle impact position on the scintillator modu les. The results from the beam test data will be used for the design o f the readout and trigger electronics in conjunction with the required ALR performance as an electron tagger and beam background monitor at LEP II.
