Abstract

We have evaluated the performance of a Ce-doped fused-silica fiber as wavelength shifter coupled to a CeF3 crystal using electron beams at CERN. The pulse shape and collection efficiency were measured using irradiated (100 kGy) and un-irradiated fibers. In addition, we evaluated the light yield of various Ce-doped fibers and explored the possibility of using them in the future, including for precision timing applications in a high-luminosity collider environment.
