In-space electric propulsion technologies have advanced significantly in the last decade,
while there has been increasing interest in economical propulsion systems with growing …

We demonstrate a technique by which erosion of the acceleration channel in Hall thrusters
can be reduced by at least a few orders of magnitude. The first principles of the technique …

Faraday probes are a common plasma diagnostic used to determine the local ion charge
flux of electric propulsion plumes. Standard practices, guidelines, and recommendations are …

Novel hexagonal boron nitride (h-BN) matrix composite ceramics exhibit versatile and
greatly improved properties compared with the traditional h-BN ceramics, such as excellent …

The high efficiency multistage plasma-thruster (HEMP-T) represents an ion thruster
technology that was developed by Thales Deutschland GmbH beginning in the early 2000s …

An overview of low temperature, partially magnetized ion sources is presented. This class of
devices is broadly characterized by plasma densities below 10 19 m− 3, electron …

We employ the 2D (r–z) code Hall2De to conduct numerical simulations of the SPT-140, a
Hall thruster that operates with an external hollow cathode. The simulations are informed by …

A proof-of-principle effort to demonstrate a technique by which erosion of the acceleration
channel in Hall thrusters can be eliminated has been completed successfully. The first …

I. Introduction o demonstrate high-power, high-specific-impulse performance for the Asteroid
Redirect Robotic Mission (ARRM), both in terms of desired mission capability and required …

A 60 wt% boron nitride (BN)–40 wt% silica (SiO 2) hot-pressed composite, denoted as M26,
was used as the insulating chamber wall for a xenon plasma Hall-effect thruster operated for …
