A description of the monitoring system used in the KEMA subcritical suspension reactor for measuring the neutron flux in the range 2 x 10/sup 3/ to 2 x 10/sup 6/ neutrons/cm/sup 2//sec is given. For this purpose, an ionization chamber and a vibrating-capacitor electrometer are used. The sensitivity of the electrometer is stabilized by strong negative feedback (loop gain 50); the meter has six measuring ranges and a linear scale. The minimum and maximum currents that produce full deflection are 5 x 10/sup -10/ and 1.6 x 10/sup -7/ am p, respectively. A calibrating device is incorporated for checking the operation of the instruments at any time. The monitoring system consists of two identical channels; each channel is powered from its own battery.
