An improved method and system of pulsed mode operation of ionization chambers in which a single sensor system with gamma compensation is provided by sampling, squaring, automatic gate selector, and differential amplifier circuit means, employed in relation to chambers sensitized to neutron plus gamma and gammaonly to subtract out the gamma component, wherein squaring functions circuits, a supplemental high performance pulse rate system, and operational and display mode selection and sampling gate circuits are utilized to provide automatic wide range linear measurement capability for neutron flux and reactor power and wherein neon is employed as an additive in the ionization chambers to provide independence of ionized gas kinetics temperature effects, and wherein the pulsed mode of operation provide independence of high temperature insulator leakage effects. |
