| Abstract: | We have designed a neutron measurement system with the preamplifier separated from the detector. The electronic circuit with poor irradiation resistance from the detector assembly is isolated, and connected remotely through a coaxial cable. The test results show that, the maximum relative inherent error of the probe is only 8.6%, and the difference between the relative response of the Am-Be source and the 252Cf source is 9%. Its performance meets the design requirements. |
