The performance of an iodine radio ion thruster with a 4 cm diameter (IRIT4) was studied experimentally in this paper. Regulation of the mass flow rates of the iodine propellant is achieved by using a temperature control method of the iodine reservoir. Performance of the thruster using iodine as propellants is obtained at different total thruster powers of 40.6–128.8 W, different grid voltages of 1000–1800 V and the iodine flow rate of 100 μ g s −1 . Results show that thrust and specific impulse increase approximately linearly with the increasing total thruster power and the screen grid voltage. The thrust of 2.32 mN and the specific impulse of 2361 s are obtained at the nominal total thruster power of 95.8 W and the screen grid voltage of 1800 V. It is also indicated that performance of the iodine propellant is comparable to that of the xenon propellant; and a difference between them is that the iodine thrust is slightly higher than xenon when the total thruster ...

4厘米碘加氢射频离子推进器的性能

本文通过实验研究了直径为4 cm的碘放射性离子推进器（IRIT4）的性能。碘推进剂的质量流量的调节是通过使用碘储存器的温度控制方法来实现的。在不同的推进器总功率40.6–128.8 W，不同的电网电压1000–1800 V和碘流量100μgs -1的情况下，可获得使用碘作为推进剂的推进器性能。结果表明，推力和比脉冲随总推进器功率和屏蔽栅网电压的增加而线性增加。在95.8 W的额定总推进器功率和1800 V的屏蔽电网电压下，可获得2.32 mN的推力和2361 s的比冲。还表明，碘推进剂的性能与氙推进剂的性能相当。它们之间的区别是，当总推进器... ...时，碘的推力略高于氙。
