252Cf源中子辐照装置的设计及性能测试
The development of a 252Cf source-based neutron irradiation facility
【摘要】 介绍了一种具有可变准直孔低γ本底的252Cf源中子辐照装置。对其中子辐射场和中子屏蔽性能的测试结果表明,该辐照装置能够形成稳定的中子场,屏蔽体对252Cf中子源有很好的屏蔽性能。
【Abstract】 In this paper,we report the development of a 252Cf source-based neutron irradiation facility,with alterable collimation holes and reduced y-ray background.Test results of the neutron intensity distributions and the shielding performance show that the facility produces a steady neutron irradiation field with a good shielding performance.
