| Popis: | Neutron self-shielding effect in bulk materials impairs analysis of elements using prompt gamma-rays induced by thermal neutron capture reaction. For the on-line coal analysis setups of Nanjing Dalu Zhongdian Technology Joint-Stock Co., Ltd, Monte-Carlo simulations have been performed to investigate effect of the channel on correcting neutron self-shielding effect and improving measurement of H in coal. The results show that, by introducing an adequate channel in the moderator, the self-shielding effect can be corrected, and the linear concentration region of H can be extended effectively. |
