Patent ID: 8115179

Claim:
A radiation detector, comprising: an array of linear position sensors being adapted for neutron capture in a vacuum chamber and generation of a current signal based on the neutron capture; and a preamplifier circuit comprising: a first and second transimpedance amplifier coupled to receive the current signal from a first and second location on the detector, respectively, and generate a first and second voltage signal at respective outputs, and a second amplification stage having an input coupled to an output of said transimpedance amplifiers for amplifying said first and said second voltage signals to provide first and second amplified voltage signals, a differential output stage coupled to said second amplification stage, said differential output stage receiving said first and second amplified voltage signals and providing a pair of outputs from each of said first and second amplified voltage signals, and read out circuitry having an input coupled to receive both said pair of outputs, said read out circuitry having structure for processing each of said pair of outputs, and providing a single digital output having a time-stamp therefrom.
