A multi-scale approach to electrospray ion source modeling has been developed. The
evolution of a single-emitter electrospray plume in a pure ionic regime is simulated with a …

Ionic liquid electrosprays can emit a polydisperse population of charged droplets, clusters,
and molecular ions at high velocity. Secondary species emission (SSE) is a term that …

Experiments were conducted at the University of Illinois at Urbana Champaign Electric
Propulsion Laboratory to study the ion-induced secondary charge emission from surfaces …

The recent proliferation of SmallSats and their use in increasingly demanding applications
require the development of onboard electric propulsion compatible with the power, mass …

Electrospray devices, such as ionic liquid ion sources, often exhibit glows during operation
in high vacuum facilities. The lack of electron excitation mechanisms during electrospray …

Abstract Machine learning models are applied to simulated electrospray particle data to
investigate plume dynamics from emission to final particle properties. A limited set of final …
