摘要：Material effect of inner-detectors to the performances of the BESIII Electromagnetic Calorimeter
(EMC) is investigated. The Time-Of-Flight counters (TOF) has been utilized to improve the energy
resolution and detection efficiency for photons after a careful energy calibration. A matching
algorithm between TOF and EMC energy deposits is developed, and the effects of beam-related
background are discussed. The energy resolution is improved and the photon detection efficiency
can be increased by the combined measurement of EMC and TOF detectors.
