Abstract
A new code package of alpha-neutron coupled transportation is developed. It can be used to simulate the transportation of alpha particle in media, to compute the neutron yield in media contains oxygen and to track the history of the secondary neutrons. The secondary neutrons are simulated efficiently by tracking lots of neutrons with small weight, which is determined by the alpha-neutron yield. The stopping power and range of alpha particle in media are given by SRIM code, the alpha-neutron cross section is from charged particle library in JENDL, and the neutrons are treated by MCNP code.
