SUMMARY:2D Particle-In-Cell Simulation of the Narrow Channel Hall Thruster
DESCRIPTION:Lecturer:Omri Hamo\n Faculty:Department of Aerospace Engineerin
 g\n Institute:Technion – Israel Institute of Technology\n Location:Class
 room 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstract: \n
  Details: \n In the past decade growing numbers of nanosatellites are bein
 g used in space\, with an-ever increasing mission demands. Nevertheless\, 
 due to severe limitations on on-board power\, there is currently a gap in 
 propulsion solutions for these miniaturized spacecraft. To address these i
 ssues\, a very low power Hall effect thruster known as the narrow channel 
 Hall thruster (NCHT) was recently developed and demonstrated at the Aerosp
 ace Plasma Laboratory (APL)\, Technion. Due to the small dimensions of the
  NCHT channel (1 mm wide and 2 mm in length) experimental measurements of 
 the thruster discharge are very challenging.\nIn this work we study the th
 ruster using a particle-in-cell (PIC) simulation XOOPIC-APL. The original 
 code was modified to provide 2D spatial distributions of the plasma parame
 ters inside the thruster channel. The global performance figures obtained 
 from the simulation are shown to be in excellent agreement with the experi
 mental measurements.\nThe talk will be divided into two parts: first we pr
 esent the numerical techniques that were used to improve the code executio
 n\; second\, we analyze the simulation results.
