| 中文摘要: |
| 慢化体准直器是热中子照相装置的关键组件之一,利用铅、铍、石墨等为慢化体的材料,对d-T反应中子源中子照相装置的慢化准直系统进行设计.采用MCNP程序模拟d-T反应快中子在慢化体内的中子慢化输运过程,通过计算得到了满足热中子照相的慢化准直系统的设计方案,给出了经慢化后的中子束各项物理参数. |
| 英文摘要: |
| Moderator-collimator is a key assemble of thermal neutron radiography facility.By using lead,beryllium,and graphite as moderator materials,the moderator of thermal neutron radiography system,which utilizes d-T neutron generator as source,is designed.The neutron slowing and transport process in moderator was calculated by MCNP program.By calculating,the Moderator-collimator design plan which meets the thermal neutron radiography is gained.The performance parameters of the neutron beam after moderator is also given. |
