摘　　要：国际热核实验堆ITER FEAT设计已完成。在ITER中,α粒子诊断是运行控制方面的一个关键性问题。从Kuteev的氢类靶丸消融理论出发,导出了杂质靶丸的半径烧蚀速率和粒子消融速率,并对杂质靶丸注入在未来ITER中作为α粒子诊断的可行性进行了探讨。计算和理论分析表明锂靶丸具有较多兼容性,既可用作α粒子诊断也可测量等离子体的q分布。New design details for the International Thermonuclear Experimental Reactor,ITER-FEAT,have been completed.The α particle diagnostics is one of the key issues for controlling the operation of fusion reactor. Based on the two dimensional kinetic ablation theory of hydrogenic pellet developed by Kuteev, a new algorithm for erosion speed and ablation rate calculations of the impurity pellets in reactor-relevant-plasma bas been derived. Preliminary exploration for the feasibility of application of impurity pellet injection to the α particle diagnostics in future ITER device has been performed. Comparisons and analysis of the numerical integral calculation results show that the lithium pellet injection possesses much more compatibilities. It might be feasible to apply this technique to both α particle diagnosis and safety factor q(r) profile measurement in the future ITER device.
