The numerical code Hybrid-PIC Hall, a 2D hybrid particle-in-cell model, is used to simulate an axisymmetric cross section of the plasma acceleration zone. A set of nine HP Hall simulations are run using three different cathode positions and Bohm electron mobility coefficients to study the effects of these parameters on ion acceleration. Six additional cases were run in an attempt to better match the simulation results to the experimental data. For model validation, agreement between the numerical and experimental results is examined. The results show that it is difficult to match both the global operational parameters (i.e, thrust, discharge current, and beam current) and the ion velocity distributions. The shape of the axial velocity distributions can be closely matched by using high Bohm electron mobility values. However, this correlation comes at the expense of peak ion velocity and discharge current agreement. Radial velocity distributions are more closely matched by the simulations, but the simulations uniformly predict lower than measured inward and higher than measured outward radial velocity components (relative to the centerline) from the annular acceleration channel.

Experimental and Numerical Examination of a Hall Thruster Plume (Preprint)

“…As discussed in Ref. 29, this case produced the best agreement with LIF measurements at the exit plane. Input data for the plume simulation was obtained by sampling particles crossing the exit plane.…”

“…A detailed sensitivity study of HPHall as applied to the BHT-200-X3 thruster was presented in Ref. 29. The input conditions corresponded to the "low mobility, near cathode" case.…”

“…These data have been used extensively for model validation. [22][23][24][25][26][27][28][29] The experimental data from this effort are compared to simulations of the plume performed using plasma plume model DRACO. DRACO is an electrostatic particle-in-cell (PIC) code used to simulate plume of electric propulsion devices.…”

Multi-Scale Modeling of Novel Hall Thrusters: Understanding Physics of CHT and DCF Thrusters

“…Draco supports variety of source models, including one developed specifically for interfacing with HPHall. 25 This model takes as its input a file containing a large number of [r, v z , v r , v θ ] tuples. The source randomly selects a tuple from the list and rotates it through a random azimuthal angle θ.…”
