摘要
One new neutron flux density detector was studied .Its principle was to mea‐sure annealing heat from mineral depositional energy to make sure neutron flux density . The new neutron detector was calibrated ,the measuring neutron flux density of certain location in reactor was 5.108 × 1011 cm -2 ?s-1 ,and the measuring value and calibrated neutron flux density (5.000 × 1011 cm -2 ?s-1 ) were coincidence in the 2% .The results show that the new neutron detector can use to measure neutron flux density . T his neutron detector has the advantages of small volume possession in nuclear reactor with required shape , and simplified multi‐point measurement . The detector can measure different energy neutron flux densities if select element is sensitive for corresponding energy neutron .
