EIC Scintillating Fibers for Barrel Imaging Calorimeter

BSA, LLC is looking for sources to provide scintillating Fibers. 3.1 Technical/Performance Characteristics Light yield: the average response to a Sr-90 source shall be greater than 5 photoelectrons measured using a bialkali photomultiplier tube 200 cm from the source, and the opposite end blackened (assessed via methods mutually acceptable to the BSA and Contractor). Diameter mean value and variation shall be 1.00 +/- 0.01 mm, RMS ≤0.02 mm. Attenuation length for blue light > 4m. Batch to batch or lot to lot variation of light yield <15%. Batch to batch or lot to lot variation of attenuation length <10%. Emission spectrum in blue-green light Scintillation decay time <3ns Total length ~4500 km Delivery method in cans. Length of fibers 4.55 meters +/- 0.01m.
