Abstract

1,023,117. Detecting neutrons. ATOMIC ENERGY OF CANADA. June 19, 1964 [July 29, 1963], No. 25504/64. Heading G6P. A neutron flux measuring device is formed of an electron emitter electrode and a collector electrode separated by a solid insulator. The emitter generates an electron current when subjected to a neutron flux and a potential difference is developed across a load resistor, connected between the two electrodes, proportional to the emitter current. A coaxial cable connects the electrodes to an indicating instrument and in order to reduce the effect of " background " signals, due to the incidence of radiations upon the cable, a second similar cable is mounted adjacent to the first. The " background " signals generated in the two cables are applied in opposition to the indicator. The emitter material may be aluminium, vanadium, silver, cadmium or gadolinium.
