The transition from old space to new space along with increasing commercialization has a
major impact on space flight, in general, and on electric propulsion (EP) by ion thrusters, in …

This article provides information about the sizing and standardization of a Faraday cup (FC)
used as a plasma diagnostic. This instrument is used to accurately map the ion beam profile …

Compact micronewton thrusters can provide attitude control for small satellites to increase
mission duration and enable constellation flying. Micronewton thrust control can also …

After launch in Dec 2018, the first propulsion system based on liquid metal Field Emission
Electric Propulsion (FEEP) was successfully demonstrated in orbit in 2019 in an IOD …

This paper investigates whether biased electrodes can improve the performance of a
microwave-discharge water ion thruster, which has been proposed as a propulsion system …

After the first launch of an ENPULSION NANO thruster in 2019 together with FOTEC1, 2, 3,
which verified for the first time the operation of a propulsion system based on liquid metal …

This manuscript discusses the on orbit data availability and system integration aspects of the
ENPULSION NANO liquid metal FEEP propulsion systems. We present flight data from …

Many low-Earth-orbit constellations consist of multiple small satellites that are launched
together in batches, and which make use of differential atmospheric drag for subsequent …

Ion-induced electron emission (IIEE) is an important process whereby ions impinging on a
material surface lead to net emission of electrons into the vacuum. While relevant for …

This work provides measurements of the ion-induced electron emission yield caused by keV-
range energy indium ions (3–8 keV). In our experiment, the ion sources, fueled with indium …
