Abstract: Abstract: A prototype sampling electromagnetic calorimeter (17.1 radiation lengths) for future linear collider experiments was built, using plastic scintillator tiles and 4mm-thick lead absorber. Wavelength-shifting fibers were used to guide the scintillation light into multi-anode photo-multiplier tubes. The calorimeter was tested at the beam test facility of the High Energy Accelerator Research Organization (KEK) in 2004. In this article we present our beam test results for the tile/fiber calorimeter focusing on the linearity in energy response, the energy resolution, position resolution and uniformity across the tile front face.
