We have constructed lead scintillator sandwich calorimeters with 1/4 [chi][sub o] sampling frequency and total thickness [approximately]16[chi][sub o]. The 4 mm thick scintillator plates are read out by wavelength shifter fibers 1 mm in diameter which pass through holes penetrating the plates on a .95 cm [times] .95 cm grid (Shish-Kebab geometry). We tested these modules in the A2 test beam at Brookhaven using low energy electrons and hadrons. Results are here presented on electron energy and time-of-flight resolution obtained with various combinations of scintillators and wavelength shifters. We also describe results on e/[pi] separation obtained with a new technique for the longitudinal segmentation.
