  • Pulse conversion circuit
    Patent number: 4251744
    Abstract: A pulse conversion circuit which converts input voltage pulses to current pulses, compares the resulting current pulses to a threshold current and produces an output voltage proportional to the integrated difference between the current pulses and the threshold current.

  • Method and apparatus for monitoring the output of a neutron detector
    Patent number: 4103166
    Abstract: A method and apparatus for monitoring the output of an ion chamber type in-core neutron detector is disclosed. Neutron detectors of this type are known to produce both alternating current and direct current signals which are used as measures of the neutron flux in the chamber. The monitor employs a ratio of the alternating current and direct current signals to detect ion chamber leaks, to correct the output of the detector after a leak, to predict the end-of-life of the detector and to determine the non-linearity of the detector at different power levels.
