摘要

A new thermal neutron detector with a domestically produced THGEM(Thick Gas Electron Multiplier)was developed as an alternative to3 He to meet the needs of the next generation of neutron facilities. One type of Au-coated THGEM was designed specifically for neutron detection. A detector prototype has been developed and the preliminary experimental tests are presented, including the performance of the Au-coated THGEM working in Ar/CO2 gas mixtures and the neutron imaging test with252 Cf source, which can provide the reference for experimental data for research in the future.
