The Research of Comparison Ezperiment for a Digital Neutron Fluz Absolute Measure Device
In many neutron flux absolute measure experiments, nowadays, we usually use analogue measure device. But there are many shortcomings, such as complex components, heavy laboring intense of workman, long time of radioactive work and so on. Therefore, a new type digital neutron flux absolute measure device based on 4πβ-γcoincidence method which was built by Campton in 1959 and corresponding comparison experiment research work will be necessarily carried out. By comparing the experiment result of each Au foil which was respectively measured in Sichuan University and CAEP, the worst uncertainty was below 0. 5 %. According to the test results, we can easily draw a conclusion that the new type digital neutron flux absolute measure device can satisfy the users requirements. Moreover, the research materials show that such device based on digital technology not but on analogue technology is the first at home.
