兰州大学目前正在研制强流D-T/D-D中子发生器。Cockcroft-Walton加速器作为中子发生器的一部分，将用于加速来自双等离子体管离子源的大电流低能束并将其输送到旋转靶。利用TRACK程序对一条强流低能束流输运线进行了设计，并对混合束进行了动力学仿真。结果表明，所设计的束流线有利于40 mA的氚束流的顺利输运，并且使用两个光圈可以有效地减少不需要的离子数目。(C)2015爱思唯尔B.V.保留所有权利。
An intense D-T/D-D neutron generator is currently being developed at the Lanzhou University. The Cockcroft-Walton accelerator, as a part of the neutron generator, will be used to accelerate and transport the high-current low-energy beam from the duoplasmatron ion source to the rotating target. The design of a high-current low-energy beam transport (LEBT) line and the dynamics simulations of the mixed beam were carried out using the TRACK code. The results illustrate that the designed beam line facilitates smooth transportation of a deuteron beam of 40 mA, and the number of undesired ions can be reduced effectively using two apertures.
