We present a study of two di fferent sets of Micro-Channel Plates used for time and space resolved single particle detection. We investigate the eff ects of the gold coating and that of introducing an interplate voltage between the spatially separated plates. We fi nd that the gold coating increases the count rate of the detector and the pulse amplitude as previously reported for non-spatially resolved setups. The interplate voltage also increases count rates. In addition, we nd that a non-zero interplate voltage improves the spatial accuracy in determining the arrival position of incoming single particles (by 20%) while the gold coating has a negative e ect (by 30%).
