NASA's Evolutionary Xenon Thruster (NEXT) is a gridded-ion thruster. In an ion thruster, ions are accelerated by electrostatic forces. The electric fields used for acceleration are generated by electrodes positioned at the downstream end of the thruster. Each set of electrodes, called ion optics or grids, contains thousands of coaxial apertures.

Thrust generated by ion thrusters, as shown in gure 1.1 [6], is done by electrostatically accelerating ions through grids located at the end of the discharge chamber. 1.1 Ring-Cusped Ion Thruster A diagram of a typical ring-cusped ion thruster is shown in gure 1.2. The discharge chamber is where the ionization occurs. Three magnetic ... An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion.It creates thrust by accelerating ions using electricity.. An ion thruster ionizes a neutral gas by extracting some electrons out of atoms, creating a cloud of positive ions.These ion thrusters rely mainly on electrostatics as ions are accelerated by the Coulomb force along an electric field. Fundamentals of Electric Propulsion: Ion and Hall Thrusters March 2008 The research described in this publication was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under

A labeled diagram of the Dawn spaccraft. With its wide solar arrays extended, Dawn is about as long as a tractor-trailer at 65 feet (19.7 meters). The ion thruster is powered by large solar panels. The power ionizes the fuel (Xenon) and then accelerates it with an electric field between two grids. Ion and Hall thrusters that utilize an electron discharge to ionize the propellant gas and create the plasma in the thruster require a cathode to emit the electrons. In addition, thrusters must neutralize the ion beam leaving the thruster by providing electrons emitted from a cathode into the beam. The properties of the Diagram of a typical gridded ion thruster, the NSTAR The typical gridded ion thruster is the Kaufman type. Its operation can be divided into ionisation, acceleration, and neutralisation. Ionisation: Xenon is most commonly used as the propellant. Session 10-11: Electrostatic Thrusters (Kaufman Ion Engines) Electrostatic thrusters ("ion engines") are the best developed type of electric propulsion de­ vice, dating in conception to the 1950's, and having been demonstrated in space in 1964 on a suborbital flight of the SERT I spacecraft. The early history and concepts are well doc­

The ion thruster then processes the propellant and power to propel the spacecraft. The first ion thrusters did not last very long, but the ion thruster on Deep Space 1 exceeded expectations and was used more than 16,000 hours during a period of over 2 years. The ion thrusters being developed now are being designed to operate for 7 to 10 years. NSTAR engine diagram. NSTAR is an electron bombardment thruster - a type of ion propulsion system - developed by NASA and Hughes Research Laboratories (now part of Boeing). It was used to propel the Deep Space 1 probe. Although NSTAR works in the same way as its commercial counterpart, XIPS, which is used mainly for satellite station ... the ion beam during the thrusting periods. Fig. 1-1 shows a block diagram explaining the operating principle of a RIT thruster. 1.2 Discharge Ignition and Operation To start the thruster the neutraliser will be set in operation first. After ignition of the neutraliser discharge the mass flow into the thruster will be started and the RF- Dawn Thruster Block Diagram Figure 2 shows a block diagram of Dawn's ion thruster. The basic construction is reminiscent of the electron gun in an old tube-type television. The thruster concept is simple: supply xenon from the propellant supply bottle to the ionization chamber ionize the xenon
