Schematic view of the beamline setup.
Event display of typical events. Left and center pictures are ScECAL display for a 32~GeV muon and 16~GeV electron events. Right one is ScECAL+AHCAL+TCMT combined view of a 16~GeV pion event.

Event display of a typical $\pi^0$ candidate, and invariant mass distribution reconstructed from two electromagnetic clusters on the ScECAL.
Electron energy spectra measured on the ScECAL. Unit of horizontal axis is given in MIP equivalent response.

Scintillator-strip response to the minimum ionising particles as a function of hitting position. Left plot is obtained at beam test of first prototype in 2007 at DESY. With this plot the MPPC is attached at right end of the plot. Right plot is a result from the 2008 Fermilab beam test. The MPPC is located at position of zero (left end of the plot).
