碘是下一代离子推进器的一种有吸引力的推进剂。激光诱导荧光（LIF）作为一种非微扰技术被广泛应用于推力器预测模型的流量测量。我们将最近证明的用于单电离碘的LIF方法应用于磁化等离子体环境，类似于在离子推进器和磁约束实验室等离子体中发现的环境。我们证明了从I+的塞曼效应-分裂谱中远程确定局部磁场的可行性。
Iodine is an attractive propellant for next generation ion thrusters. Laser induced fluorescence (LIF) is widely used with other propellant species as a non-perturbative technique for measuring flow for thruster prediction models. We apply LIF methods recently demonstrated for singly-ionized iodine to a magnetized plasma environment similar to those found in ion thrusters and in magnetically confined laboratory plasmas. We demonstrate the feasibility of remotely determining the local magnetic field from the Zeeman effect-split spectrum of I+.
