氘束与厚靶相互作用产生高能中子

Productions of high energy neutrons by interactions between deuteron beam and thick target

Wu Sun, Weiwei Qiu, Jun Su

摘要:

高能中子感生裂变的截面对研究长寿命裂变产物的嬗变是有用的。但由于高能中子难以获得,实验数据仍然匮乏。本文研究了氘束与厚靶相互作用产生高能中子的可能性。利用Geant 4工具包模拟了氘束与厚靶的相互作用。本文还发展了一种计算氘束与厚靶相互作用中中子产额的解析方法。输入的截面数据不仅取自TEDNL-2017库,而且还通过同位旋相关的量子分子动力学模型计算。结果表明,氘束与物质相互作用产生高能中子是可能的。如果要获得高能量中子,可以考虑低Z物质、薄靶和小发射角。

英文摘要:

The cross sections of high energy neutron-induced spallation is useful for studying the transmutation of long-life fission products. However, due to the difficulty of obtaining high-energy neutrons, the experimental data are still scarce. The present work studies the possibility to produce high energy neutrons by interactions between deuteron beam and thick target. The Geant4 toolkit is applied to simulate the interaction between the deuteron beam and thick target. An analytical method is also developed to calculate the neutron yields emitted in the interaction between the deuteron beam and thick target. The input cross section data is not only taken from the TEDNL-2017 library but also calculated by the isospin-dependent quantum molecular dynamics model. It is indicated that it is possible to produce high energy neutron by deuteron beam interaction with matter. If one wants to get high energy neutrons, low-Z matter, thin target, and small emission angle may be considered.
