The positively charged ions are accelerated out of the thruster as an ion beam, which produces thrust.
This is a very similar concept in many ways to the ion drive, in that it uses the electrostatic effect to accelerate propellant, but the mechanism is very different. The difference in engine type arises through performance requirements: typically HETs are used for higher thrust E Consortium Partners include the ArianeGroup, QinetiQ, OHB, CRISA / Airbus Defence and Space, AST – Advanced Space Technologies, Mars Space and the University of … An ion thruster produces a flow of air even though it has no moving parts. Inventors at Georgia Tech have developed a mechanical method to store a high-performance gridded ion thruster in a small volume compatible with the dimensions of a small (cubesat/nanosat) spacecraft for efficient storage during launch to orbit.
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 thrusters.
Dual-stage Gridded Ion Thruster (DS4G) Figure 1.
A version of this seemingly impossible device is used on a larger scale to propel deep space probes for NASA. As per request, i am adding block weight for both large and small grids Large Default 'Ion' Thruster It is a larger thruster than its predecessors with an open grid area of 30 cm.
T7 Gridded Ion Thruster.
The advantage to this system over others is that you need only an electrical source to power the device and it has no moving parts so it is almost unbreakable. 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 contract with the National Aeronautics and Space Administration. We are partners of the GIESEPP consortium which is supported by the European Union’s Horizon 2020 research and innovation programme. Electrostatic grid systems used in conventional state-of-the-art ion thrusters perform ion extraction and acceleration simultaneously in a single-stage process, typically using 2 or 3 permeable grids closely spaced in series.

Hall Effect Thrusters. The T7 thruster is a ring-cusp DC discharge, gridded ion thruster, and its development builds upon the heritage of the current T5 and T6 Kaufman type ion thrusters developed by QinetiQ. 
They use electricity to generate thrust, their power consumption scales linearly with what percentage (as seen on the thrust override slider) the thruster is operating at. Today, gridded ion engines from the USA, and Hall Effect Thrusters (HET) from both the USA and the EU, are being selected for geostationary telecommunication missions. The order i will do, is the type of thruster - Then the large grid thrust (LGT) - and then the small grid thrust (SGT), so that others who struggled like me will know how many thrusters they're going to need to lift a certain weight.
When the US was beginning to investigate the gridded ion drive, the Soviet Union was investigating the Hall Effect thruster (HET). QinetiQ Kaufman Gridded Ion Engines T6: 5 kW class thruster •22 cm active grid area •Thrust capability 30mN to 230 mN –Grid set can be optimised for different thrust ranges High Isp >4000s •> … The neutralizer, another hollow cathode, expels an equal amount of electrons to make the total charge of the exhaust beam neutral. GIESEPP (Gridded Ion Engine Standardised Electric Propulsion Platform) Consortium.
and started flying Gridded Ion Engines in the late 1990s. All standard Electric-based Ion thrusters will consume a minimum of 0.002 kW (2 Watts), even when not in use. Once the spacecraft is ejected from the launch vehicle, the gridded ion thruster is deployed to its full operational geometry and
