Abstract

Extruded scintillator with co-extruded hole and reflective coating will be used both in MINERvA and T2K experiments. We have studied WLS (wavelength shifting) fibers (Y11 and Y7) for different shapes of the extruded scintillator readout using MRS (Metal/Resistor/Semiconductor) photodiode. The Y7 fiber was considered because of its lower then Y11 cost. The purpose was to find out which fiber performs better in above configurations. First, the responses for both types of fibers, with and without optical grease, were measured by PMT (Photomultiplier Tube). The PE (photoelectron) yield from cosmic rays for different scintillator shapes and both fiber types, as seen by MRS photodiode, are reported. The attenuation lengths of Y11 and Y7 were measured using MRS Photodiode. Y7 fiber shows somewhat better performance at short distances from the photo detector, while Y11 performs better at larger lengths.
