A highly granular electromagnetic calorimeter with scintillator strip readout is being developed for future linear collider experiments. A prototype of 21.5𝑋0depth and180 × 180 mm2transverse dimensions was constructed, consisting of 2160 individually read out10 × 45 × 3 mm3scintillator strips. This prototype was tested using electrons of 2–32GeVat the Fermilab Test Beam Facility in 2009. Deviations from linear energy response wereless than 1.1%, and the intrinsic energy resolution was determined to be(12.5±0.1(stat.)±0.4(syst.))%∕√𝐸[GeV]⊕(1.2±0.1(stat.)+0.6−0.7(syst.))%, where the uncertainties correspond to statistical and systematic sources, respectively
