这项研究展示了10W级微型离子发动机，包括离子束中和器。这款微型离子发动机有两种中和器选择。一种是使用与离子推进器相同的放电室的中和器。另一种是使用特殊的栅极系统，通过外部的电气开关来选择离子束的引出和电子发射。此选项通过取消中和器设备来降低性能，从而有助于减轻系统重量。对这两个选项的中和性能和所产生的总体系统性能进行了检查。给出了固定推力下的总功率消耗与比冲之间的关系。
This study shows 10-W-class miniature ion engine including ion beam neutralizer. This miniature ion engine has two options for the neutralizer. One is to use a neutralizer using the same discharge chamber as the ion thruster. The other is to use a special grid system from which ion beam extraction and electron emission is selected by the outside electrical switching. This option contributes to reduce system weight by eliminating the neutralizer device in exchange for decreasing the performance. Neutralization performance and resulted total system performance were examined for both options. As a result, relations between total power consumption and specific impulse are given at fixed thrusts.
