The CREAM (Cosmic Ray Energetics And Mass) experiment was constructed for the measure-ment of high-energy cosmic rays in the energy range between 1012 and 1015 eV. As a long duration balloon payload, the CREAM had its first successful flight in December 2004 fromMcMurdo Station, Antarctica. For the charge measurement of incident cosmic-ray particles entering the calorimeter module, a layer of the SCD (Silicon Charge Detector) made of 2912 silicon pixels was built with an active area of 779 × 795 mm2. This paper describes the performance of the SCD during the 2004-2005 flight.
