    Abstract: PURPOSE:To make possible an accurate measurement of radiation without depending upon the magnitude of a counter ratio by setting a pulse amplifier which can control a gain by a current flows through a Geiger-Muller (GM) counter. CONSTITUTION:When a radiation is incident on a GM counter 1 to form a current path in the GM counter 1, a current flows in a route of the second resistor 2, the GM counter 1, and the third resistor 11 as a GM current detection circuit which detects the GM current flows in the GM counter 1. As the result, a voltage proportional to the GM current is appeared at both ends of the resistor 11. When the radiation incident on the GM counter 1 increases, the GM current also increases, thereby increasing the voltages of both ends of the third resistor 11. In this case, the decrease of the value of a wave crest of the pulse signal appears at the negative side of a capacitor 5 is corrected by increasing the gain of a pulse amplifier 6 detecting the increase of the GM current. Thus, the value of an output wave crest of a gain automatic controlling pulse amplifier block 13 becomes always constant and the accurate measurement is possible.

    Abstract: An in-core nuclear detector for detecting the neutron population surrounding the detector. The detector is an ion chamber having a cylindrical outer electrode that is insulated from a central electrode and capped to contain an Argon gas. An electron radiator that produces prompt neutron capture gamma radiation that is substantially, directly proportional to the local neutron population is disposed between the outer tubular electrode and the central electrode.
