“…Nowadays PIC codes are used in different research areas, for example in laser-plasma simulations, in plasma acceleration and also in space applications (Lapenta et al 1995). In particular, during the European HPH.COM program, at the University of Padova different codes were developed (Pavarin et al 2011;Manzolaro et al 2012;Cardinali et al 2014;Fabris et al 2015), for the detailed design and optimization of plasma thrusters of the helicon type (Manente et al 2019). In order to obtain a unique and global tool able to simulate the whole plasma discharge we have developed a new two-dimensional (2-D) electrostatic PIC code named EDI (enhanced biDimensional pIc).…”

EDI (enhanced biDimensional pIc) is a two-dimensional (2-D) electrostatic/magnetostatic particle-in-cell (PIC) code designed to optimize plasma based systems. The code is built on an unstructured mesh of triangles, allowing for arbitrary geometries. The PIC core is comprised of a Boris leapfrog scheme that can manage multiple species. Particle tracking locates particles in the mesh, using a fast and simple priority-sorting algorithm. A magnetic field with an arbitrary topology can be imposed to study the magnetized particle dynamics. The electrostatic fields are then computed by solving Poisson’s equation with a a finite element method solver. The latter is an external solver that has been properly modified in order to be integrated into EDI. The major advantage of using an external solver directly incorporated into the EDI structure is its strong flexibility, in fact it is possible to couple together different physical problems (electrostatic, magnetostatic, etc.). EDI is written in C, which allows the rapid development of new modules. A big effort in the development of the code has been made in optimization of the linking efficiency, in order to minimize computational time. Finally, EDI is a multiplatform (Linux, Mac OS X) software.

“…A 2D Particle-in-Cell (PIC) simulation conducted by HIT Plasma Propulsion Lab (HPPL) has showed that the axial electron current density near the channel axis is much higher than that at other regions 7 . By other PIC simulations, the uneven radial distribution characteristic of the thruster has also been validated [8][9][10] . As for the experiments, the researchers from MIT took the photos of the discharge channel of the Diverging Cusped Field Thrusters by high speed camera, and it is found that the luminosity near the center of the anode is higher than other regions of the anode 11 .…”

The cusped field thruster is a newly emerging electric propulsion device. A radial non-uniformity of current density is supposed at the anode. To further study the anode current density distribution, a multi-annulus anode is designed to directly measure the anode current density for the first time. With the increase of the radial position, the anode current density decreases sharply. The magnitude of the central annulus anode current density is far higher than the other annulus. When increasing the anode voltage, ratio of the current of central annular occupying the total anode current will increase. But the non-uniformity of the anode current density change limitedly by altering anode gas flow rate.

In the framework of the "Helicon Plasma Thruster for Space Missions -AO7048" research program, a zero-dimensional numerical model is developed in order to assess the propulsive performances of the plasma thruster when fed with different molecular gases as propellants.The zero-dimensional model developed consists of detailed kinetic schemes for bulk plasma reactions and surface processes; particle in cell simulations are performed to properly describe the behaviour of the charged particles at the exhaust plume so to obtain exhaust parameters for the global model. Given a set of input parameters, such as geometry and mass flow rate, the model is able to follow the time evolution of plasma main physical quantities, such as neutral and charge densities and the electron temperature, and to calculate thruster performances. The model is then linked to the genetic algorithm optimization toolbox in Matlab environment in order to obtain high performance configurations. Propellants considered are H 2 , O 2 , N 2 and N 2 O.
