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 …

Electrospray thrusters fulfill the main propulsion requirements for long-term small-satellite
missions. However, the molecules present in the plume are susceptible to collisions …

ElECtRosPRAY systems utilize ionic liquid propellants to generate thrust from polydisperse
ion plumes (∑ i= 1 qi/mi) 1. When a potential difference on the order of a few kilovolts is …

Nanodroplet collisions with solid surfaces can occur in various applications of electrospray
technology. In electrospray propulsion, the deposition and splashing of droplets from the …

Ionic liquid ion sources (ILISs) produce charged particle beams by using a strong electric
field to extract and accelerate molecular ions and ion clusters from liquid propellant. The …

The ion plume of an electrospray thruster is known to contain multiple species, individual
ions, and clusters of ions with one or more neutral molecules attached1. These larger …

In this work, we employ combined numerical and experimental approaches to determine the
chemical composition of secondary molecular species generated through particle-wall …

The authors identified an error in the y coordinate of one of the carbon atoms that constitute
the imidazolium ring of the molecule EMI+. This error makes the imidazolium ring weaker …

The current study uses molecular dynamics modeling to identify and quantify the different
types of processes that can ensue from the collisions between the monomer ions and the …

Plume-surface interactions are an important field of study for electric propulsion devices of
all types. High-energy (keV) plume species impacting a surface can result in many possible …
