Abstract:
    A monitor of fusion neutron flux is formed by three fission chamber detectors set in stainless steel shell. It is featured as coating different mass of high purified fission material on cathodes of two fission chamber detectors make their sensitivity be 1: 100, setting the third fission chamber detector to be blank detector with no fission material, setting a layer of Cd-heat neutron shielding layer with neutron moderator structure in shell, setting lead shielding layer in neutron moderator structure and placing three fission chamber detectors in lead shielding layer.
