100～500 keV能区⁹Be(d,n)¹⁰B反应中子产额及角分布测量

摘要: 金属铍具有较稳定的理化性质，同时也易与入射的轻核粒子发生反应产生中子，在小型中子发生器的研制中具有其他靶材所不具有的优势。 ⁹Be(d,n)¹⁰B反应的中子产额和中子角分布数据，尤其是低能区的数据，对小型中子发生器的设计非常重要。本文在中国原子能科学研究院的600 kV高压倍加器上测量了100~500 keV能区⁹Be(d,n)¹⁰B反应的中子产额和中子角分布。

Abstract: Because of the stability and high neutron yield, metal beryllium can be used as the neutron source target in portable neutron generator. However, the yield and angular distribution of ⁹Be(d,n)¹⁰B reaction are not available in the low energy range, which is important for the design of portable neutron generator. The neutron yield and angular distribution at 5 energy points between 100 keV and 500 keV were measured at 600 kV CCW accelerator in CIAE.
