The results show that the beam potential with respect to the ambient in a vacuum chamber is different from that in space because the facility plasma can prematurely terminate the plume expansion process. As a result, the plume potential measured in a vacuum chamber may be significantly lower than that under the in-space condition. This can lead to underestimation of the backflow of charge-exchange ions and ionized contaminants in plasma thruster plume modeling.Read More
