Review of alternative propellants in Hall thrusters
Vlad-George Tirila,A. Demairé,Charles Ryan +2 more
TL;DR: This review compares alternative propellants to conventional xenon in Hall thrusters, considering noble gases, molecular propellants, and condensable elements, and presents a comprehensive database of experimentally measured performance for various propellants and system sizes.

Characterization of multi-jet electrospray systems
TL;DR: In this paper, the authors used a simple model that links these observations to predict the maximum number of jets that may be obtained in the type of multi-jet processes observed here, in which each jet in multi-joint mode is unable to support the same volumetric flow as in the single jet mode; indeed it appears that there is a maximum total flow that can be maintained in an electrospray, independent of the number of jet through which the flow is achieved.

Plume Composition Measurements of a High-Emission-Density Electrospray Thruster
TL;DR: An electrospray thruster designed for nanosatellites is introduced in this paper, which has a compact size featuring a passive propellant transport method through the use of porous materials.

Effect of emitter geometry on flow rate sensitivity to voltage in cone jet mode electrospray
TL;DR: The effect of voltage on flow rate within cone jet mode electrospraying has been investigated in this paper, with particular emphasis on the effect of emitter geometry and hydraulic resistance of the flow system.

The influence of geometry on the flow rate sensitivity to applied voltage within cone-jet mode electrospray
TL;DR: In this article, the effect of geometry on the relationship between emitted flow rate and applied potential difference in cone-jet mode electrospray systems is investigated in greater detail than in previous studies.
