The equality of the phase errors is shown. The relationship between the charge noise amplitude of electrodes and the total charge noise amplitude is provided. The relationship between the phase error and the total charge noise amplitude is also provided, which reveals the magnitude of 10 4 electrons for the ghosting occurrence threshold for the 4-coarse-pixel anode imagers.展开更多
