Inferring Thermal Dissociation Kinetics of Ion Clusters from Molecular Dynamics
Nicholas Laws, Adler Smith, Elaine Petro
Electrospray ionic liquid ion sources operating in the pure ion regime emit metastable, low solvation number ion clusters whose post-emission dissociation modifies plume compositio…
On the Two-Dimensional Structure and Asymmetries of Ionic Liquid Electrospray Plumes
Zach Ulibarri, Giuliana Hofheins, Sophia Gessman +1
Vacuum electrosprays play important roles in electrospray propulsion, a type of spacecraft electric propulsion wherein charged ions or droplets are accelerated at high velocity to…
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…
Electrospray Propulsion Time-of-Flight Secondary Ion Mass Spectrometry Diagnostic
Giuliana Caramella Hofheins, Zach Ulibarri, Elaine M. Petro
The design and capability of a novel time-of-flight secondary ion mass spectrometry electrospray propulsion diagnostic is presented to investigate secondary species emission from s…
Direct Two-Dimensional Goniometric Steering of Vacuum Electrospray Ion Beams for Angular Time-of-Flight Studies
Zach Ulibarri, Elaine Petro
Here we present a novel method for two-dimensional steering of vacuum electrospray ionization beams to better understand their angular properties. Utilizing an externally wetted tu…
Propellant Discovery For Electrospray Thrusters Using Machine Learning
Rafid Bendimerad, Elaine Petro
This study introduces a machine learning framework to predict the suitability of ionic liquids with unknown physical properties as propellants for electrospray thrusters based on t…
THEO Concept Mission: Testing the Habitability of Enceladus's Ocean
Shannon M. MacKenzie, Tess E. Caswell, Charity M. Phillips-Lander +17
Saturn's moon Enceladus offers a unique opportunity in the search for life and habitable environments beyond Earth, a key theme of the National Research Council's 2013-2022 Decadal…
