The silicon charge detector (SCD) is a subdetector of the high-energy cosmic radiation detection (HERD) payload. The dynamic range of the silicon microstrip detector can be extended by the capacitive coupling effect, which is related to the interstrip capacitance and the coupling capacitance. A detector prototype with several sets of parameters was designed and tested in the ion beams at the Conseil Européen pour la Recherche Nucléaire (CERN) superproton synchrotron (SPS). The capacitive coupling fractions with readout strip and floating strip incidences were studied using the beam test data and SPICE simulation.
