We present a study of two sets of Micro-Channel Plates used for time and space resolved single particle detection. We investigate the e ffects of the gold layer and that of introducing an interplate voltage between the two chevron plates for the detection of single particles. We fi nd that the gold layer 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 fi nd that the interplate voltage leads to better spatial accuracy in determining the arrival position of incoming single particles (by 20%) while the gold layer has a negative e ffect (by 30%).
