Isolating the Effects of Microchannel Plate Parameters on the Ultimate Resolution in Time-of-Flight DetectorsThis paper examines the effects of pore sizes and bias angles of the Microchannel Plates used in Time of Flight Detectors. Experiments were done to determine how the parameters of the MCP could be manipulated to minimize time jitter to ultimately improve the detection resolution of a Time of Flight detector. Efforts to control flatness of the MCP are also discussed.
