Abstract :
The MINOS experiment is a long-baseline, neutrino-oscillation experiment. In total, 28000 m2 of scintillator is needed for the experiment. This is almost 300 tons of finished scintillator. The solution has been the development of an extruded scintillator with a 2 mm deep grove in the upper surface for a wavelength-shifting fiber and a co-extruded TiO2 coating as a reflector. The TiO2 coating also allows the scintillator to be directly epoxied into panels. Production and quality control techniques are presented
