Charge equalizing and error estimation in position sensitive neutron detectors

The conventional design of detector electronics for resistive wire position sensitive neutron detectors (PSD) using of-the-shelf charge sensitive preamplifiers and gauss-pulse shaping devices causes uncertainty in spatial position and resolution due to charge equalization between both ends of the resistive PSD. This paper describes in detail charge equalization effects and their drawbacks for a PSD system design. Error estimations for a conventional design are given. Attained results should help to better understand PSD electronics design and to provide data for system optimization.
