 note = {We have fabricated an externally wetted emitter array with a deep-grooved structure using grayscale lithography for ionic liquid electrospray thrusters to improve the ionic liquid transport to the emitter tips and to reduce the percentage of the current intercepted by the extractor electrode, which was more than 30% with our conventional deep-grooved emitter. The experimental results of the ion emission have shown that a stable ion emission characteristic and the percentage of the current intercepted by the extractor electrode decreases by approximately one-third compared with our previous one. This decrease indicates that the emitter fabrication process using grayscale lithography optimized the deep-grooved emitter shape.},
