On the Two-Dimensional Structure and Asymmetries of Ionic Liquid Electrospray Plumes
Zach Ulibarri, Giuliana Hofheins, Sophia Gessman +1
Here we present the first fully two-dimensional time-of-flight (TOF) mass spectrometry survey of a vacuum electrospray plume, generated by a tungsten needle externally-wetted with…

Secondary Species formed from ionic liquid electrospray ion plume impacts with propellant thin films
Giuliana Caramella Hofheins, Aleksandra B. Biedron, Elaine M Petro
The operational lifetime of ionic liquid electrospray propulsion systems is limited by plume-extractor electrode interactions. Over time, propellant accumulation, surface erosion,…

Ab initio Simulations of EMI-BF4 Neutral-Surface Interactions in Electrospray Thrusters
Nicholas Laws, Elaine Petro
Electrospray thrusters promise compact, high specific impulse propulsion for small spacecraft, yet ground characterization remains confounded by secondary species emission and inco…
