Abstract
Long lead-scintillator sandwich modules developed for the BNL experiment KOPIO are described. The individual 4Â m long module consists of 15 layers of 7Â mm thick extruded scintillator and 15 layers of 1Â mm lead absorber. Readout is implemented via WLS fibers glued into grooves in a scintillator with 7Â mm spacing and viewed from both ends by the phototubes. Time resolution of 300Â ps for cosmic MIPs was obtained. Light output stability monitored for 2 years shows no degradation beyond the measurement errors. A 4Â m long C-bent sandwich module was also manufactured and tested.
