As small satellites become more popular and capable, strategies to provide in-space
propulsion increase in importance. Applications range from orbital changes and …

CubeSats provide a cost effective means to perform scientific and technological studies in
space. Due to their affordability, CubeSat technologies have been diversely studied and …

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

Ionic liquid ion sources utilize electric fields to evaporate and accelerate ions and ion
clusters to∼ 1 keV energies. Ion clusters may dissociate after evaporation, which is not a …

Busek's BET-300-P passively fed electrospray thruster has been experimentally evaluated
as a precision control actuator for small spacecraft. Electrospray thrusters have been shown …

The purpose of this work is to describe the use of electrospray propulsion devices as
miniaturized actuators for precise attitude control of small satellites, including CubeSats …

We present a 3D-particle-in-cell (PIC) approach to modeling electrospray plumes typical of
those formed by externally wetted emitter devices. Numerical grid-resolution techniques …

Advances in miniaturization using micromachining processes have led to propulsion
systems small enough to consider the feasibility of carrying a large number of thrusters even …

Cluster fragmentation subjected to a high-voltage electric field may play an important role in
controlling the novel ionic liquid (IL) electrospray propulsion but has received little attention …

In this work, we present coordinated molecular dynamics, ion cluster acceleration, and
retarding potential analysis simulations to determine cluster fragmentation behavior in a …
