Popis: The equations governing the charge-division encoding of a position-sensitive detector, represented as a distributed resistance-capacitance line with realistic end loading, are developed and discussed. Sources of the differential nonlinearity in the position encoding are identified and related to characteristics of the dynamic load impedances, and four practical means for reducing or eliminating such nonlinearities are proposed. The various methods for reducing nonlinearities are evaluated both by numerical solution of the circuit equations and by testing with an operating position-sensitive neutron detector and encoding system. All measurements and calculations show close agreement with one another and with the theory.
