摘要中国科学院近代物理研究所在中国加速器驱动系统（ADS）项目中进行了ADS目标站的研制工作。本文介绍了一个新开发的用于目标站设计的蒙特卡罗程序GMT1.0。该计划是专为大规模并行模拟的主动颗粒流目标的概念。GMT1.0基于INCL（Intranuclear Cascade of Leige）模型和ABLA蒸发/裂变模型的结合，集成了粒子输运程序和核反应程序，对溅射靶进行了数值模拟。为了验证，进行了一系列的计算的中子学特性和固体靶的热沉积分布，并显示出较高的精度为GMT 1.0。利用GMT1.0对靶的中子经济性进行了系统的研究，较好地说明了最佳参数的中子学特性。
Abstract The Institute of Modern Physics, Chinese Academy of Sciences performs research and development on the target station of an accelerator-driven system (ADS) under the China ADS project. A newly developed Monte Carlo program for the design of the target station named GMT1.0 is presented. The program is designed for a massively parallelized simulation of the initiative granular-flow target concept. Based on the combination of the Intranuclear Cascade of Leige (INCL) model and the ABLA evaporation/fission model, GMT1.0 integrates a particle transport code and a nuclear reaction code to simulate a spallation target. For validation, a series of calculations of neutronics characteristics and heat-deposit distributions of solid targets were performed, and a high degree of accuracy was shown for GMT1.0. Using GMT1.0, a systematic study of the neutron economy of the target was performed and the neutronics characteristics of the most optimal parameters were illustrated well.
