title: Crossed grid anode and its image partitioning.
abstract: Measurements on an imaging crossed grid anode following a pair of microchannel plates indicate fast charge propogation via wire-to-wire capacitances, suggesting a temporal resolution of 100 ns. A figure of merit for partitioned systems has been suggested that provides an estimate of the position uncertainty of photoelectrons in the image plane of an anode. Solutions for two-, three-, and four-amplifier position algorithms are given, and basic system requirements are discussed.
