Abstract
To detect the absolute neutron flux in a weak neutron field and restricted space， the fission fragment trapping detector was fabricated and the properties of the detector were studied. In this paper， the detector and shielding chamber used in neutron detection were described and the experimental measurements of the fission rate in specific condition were performed with the detection system and the result has been compared with that obtained by fission chamber. The influence of the shielding chamber on the measured results was analyzed.
