The purpose of downscaling the HEMPT design is to reach the requirements of missions which have a need for unprecedented low thrust and low noise. The aim of the here presented numerical simulations is to get an improved understanding of the thruster’s physics especially in its downscaled configuration, in order to reach the design goals. 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8-diss-224024$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/diss_mods_00022402 5051 530 5550 Cusped Field Thrusters 5550 HEMPT 5550 Magnetized Plasmas 5550 Particle-in-Cell Method 5550 Plasma Simulation
