  • Count rate measurement device and associated fission chamber calibration device
    Patent number: 9188684
    Abstract: A fission chamber count rate measurement device and to the associated fission chamber calibration device; the count rate measurement device comprises: (1) a measurement cell, which contains the fission chamber (CH); (2) a neutron generator, which emits neutrons in the form of periodic pulses towards the fission chamber; (3) a neutron counter (K), which detects and counts the neutrons emitted by the neutron generator; and (4) a computing circuit, which delivers, over a predetermined time interval, a fission chamber count rate normalized with reference to the number of neutrons counted by the neutron counter (K).
    Type: Grant

  • Method to process fission chamber measurement signals
    Patent number: 8817939
    Abstract: A method to determine the effective masses of deposits of fissile matter, including a first measuring step to measure the count rate of deposits of fissile matter of known effective masses to form a matrix [C]0, a second measuring step to measure the count rate of deposits of fissile matter to form a matrix [C], and a computing step to calculate the effective masses to be determined.
