Fundamentals of Electric Propulsion: Ion and Hall Thrusters March The research described in this publication was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

Reference herein to any specific commercial product, process, or service. High Power Electric Propulsion (HiPEP) is a variation of ion thruster for use in nuclear electric propulsion applications. [1] [2] [3] It was ground-tested in by NASA and was intended for use on the Jupiter Icy Moons Orbiter, which was canceled in An ion thruster or ion drive is a form of electric propulsion used for spacecraft creates thrust by accelerating ions using electricity.

Muhannad Eladl (US citizen) received a B.S. in Aerospace Engineering from the Georgia Institute of Technology in He started in the lab as an undergraduate student in and as a graduate student in His primary interest is in non-invasive plasma diagnostic techniques and facility effects for high-power electric propulsion devices.

All tests were conducted on a 30 cm ion thruster that was nearly identical to the NASA Solar Electric Propulsion Technology Application Readiness (NSTAR) thruster design. An ion thruster produces a flow of air even though it has no moving parts. A version of this seemingly impossible device is used on a larger scale to propel deep space probes for NASA.

An analysis for a discharge plasma is carried out on the basis of the free. The vastly improved durability of spacecrafts, coupled with the simultaneous continuous development of thrusters for high power output, has created a strong demand for Hall thrusters (HT) with long service lives.

However, erosion of the discharge channel walls by high-energy ions is the most impactful and visible process that limits the lifetime of the : Yongjie Ding, Liqiu Wei, Hong Li, Daren Yu.

An ion thruster or ion drive is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating positive ions with electricity.

The term refers strictly to gridded electrostatic ion thrusters, and is often incorrectly loosely applied to all electric propulsion systems including electromagnetic plasma.

It was ground-tested in by NASA and was intended for use on the Jupiter Icy Moons Orbiter, which was canceled in Oppose The common name would appear to be Ion Thruster which in fact the article quoted above supports; "Thruster" and even "Engine" are used more times in it than "Drive".

This is particularly true when talking about real technology which the wiki article is primarily concerned with rather than for example terminology from science fiction.

The two-stage bismuth thruster technology has several advantages for high-power operation compared with conventional single-stage Hall thrusters and high-power gas-fed gridded ion thrusters.

In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters use a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume.The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is an electrothermal thruster under development for possible use in spacecraft uses radio waves to ionize and heat an inert propellant, then a magnetic field to accelerate the resulting plasma, generating is a plasma propulsion engine, one of several types of spacecraft electric propulsion systems.
