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,…
