本文叙述了坎贝尔(Campbell)技术的原理,以及由此理论而发展起来的宽量程中子监测装置。并将此方法同一般的反应堆分区测量方法进行比较。仪器内由于采用选择器代替求和放大器,减小仪器各通道相互干扰和高功率非线性。最后对该方法在堆测量中应用前景进行讨论。 This article describes the principles of Campbell technology and the wide-range neutron monitoring devices developed from this theory. This method is compared with the general method of reactor zone measurement. Due to the use of selectors instead of summing amplifiers in the instrument, the mutual interference and high power nonlinearity of each channel of the instrument are reduced. Finally, the application of this method in heap measurement is discussed.
