Abstract

PURPOSE:To prolong a life of a detector, by using one of the two emitters for detecting neutron flux and the other emitter for recording of hysteresis of the neutron flux. CONSTITUTION:An output electric current of a self-output type neutron detector 4 having two emitters is measured by current measuring circuits 5, 6. Each value of the output current of the circuits 5, 6 is divided by the value of current at the time of early stage proofreading by dividers 7, 8 and the value is standardized. A ratio of the dividers 7, 8 is taken by a division accumulator 9 and the product of the output of the accumulator 9 and divider 8 is found by a multiplier 10 and is recorded as a function of time by a recorder 11.
