“…The success of electric propulsion utilization is based on the ability to eject a high-speed propellant and mass economy induced at launch to realize such missions. For a large overview and state-of-art of the electric propulsion topic, the reader can refer to textbooks of Jahn (2006), Turner (2009), Goebel and Katz (2008), to review articles of Ahedo (2011), Garrigues and Coche (2011), Mazouffre (2016), Levchenko et al (2018), and to recent special issues of IEEE Transactions on Plasma Sciences, vol. 43(1) (2015) and Plasma Sources Science and Technology, vol.…”

In the last thirty years, numerical models have revealed different physical mechanisms involved in the Hall thruster functioning leading to a bridge between analytical prediction / empirical intuition and experiments. For this reason, modeling effort is continuously increasing in the domain of Hall Thrusters. Two basic approaches exist: one based on fluid/hybrid simulation where the distribution of electrons is assumed Maxwellian and the plasma inside the thruster, considered as quasineutral, is described with macroscopic quantities (density, velocity and energy); the second approach is based on kinetic description for charged particles where no approximation is made for the distribution of particles. Fluid or hybrid approaches offer the advantage of demanding low run times and computational resources. They are very useful to perform parametric studies but actually the anomalous phenomena responsible for electron transport across the magnetic field barrier have not been selfconsistently modeled. Kinetic approach is able to better capture phenomena originating on the Debye scale length like the lateral sheaths, ExB electron drift instability, important to explain the anomalous electron transport, but it requires very long run times. For this latter, the progress in computer science offers the advantage to describe conditions more and more close to the thruster operation. In this review, we will present the two approaches emphasizing on numerical schemes used with assumptions and approximations and on main results obtained. Future directions on the Hall thruster modeling will finally outlined.

“…Many reviews have been written on the physics of the various propulsion systems and their respective advantages. 1,2,3 Electrostatic thrusters, such as Hall thrusters and Gridded thrusters, work on the principle of accelerating positive ions to provide moderate thrust and high specific impulse. The ion beam current and space charge need to be compensated by electrons in the downstream space to avoid charging of the satellite and cancellation of the acceleration field.…”

PEGASES is a gridded ion thruster that accelerates both positively and negatively charged ions for thrust. Halogen contained gases are used as propellant to create the two types of ions. The charged particle transport within the plasma source is controlled by a localized magnetic field such that a region described as an ion-ion plasma is formed in front of the acceleration grids. The grid system consists of two or more grids, where the first grid in contact with the plasma is biased with square voltage waveforms. The positive and negative ions are accelerated across the grids in the respective half-cycle and can be thought of as ion packets with opposite charge. These packets of bi-polar ions will quickly recombine in the downstream space forming an almost neutral beam. This electrostatic thruster does not need an additional neutralization systems and the implementation onto a space craft is therefore significantly simplified while keeping the classical advantages of EP systems such as high ISP at moderate thrust levels. Other advantages of this system are the possible control of the spacecraft charging and the almost neutral beam expelled from the thruster. Over the years much work and many papers on the physics of this innovative thruster have been published, but little have been said about the space system design and spacecraft considerations. In this paper we will therefore focus on the development, scaling and design possibilities and the conducted performance tests.
