Within the framework of three development programmes, SITAEL is currently developing a 20kW class Hall Thruster. The activities focused on increasing thruster performance and lifetime by implementing the magnetically shielded topology. Several IV10 chamber upgrades have been implemented at the beginning of the 2019, resulting in lower pressure levels in the facility. Thanks to this, it was possible to test three different channel geometries at different chamber background pressures. The results of the test were used to design a new engineering model of the thruster, to be tested by the end of the 2019. This paper presents the status of the activities on the SITAEL’s 20kW Hall Thruster propulsion system, as a part of converging efforts which are aimed at making such a propulsion system available for the space missions of the near future.

Abstract
Within the framework of three development programmes, SITAEL is currently developing a 20kW class Hall Thruster. The activities focused on increasing thruster performance and lifetime by implementing the magnetically shielded topology. Several IV10 chamber upgrades have been implemented at the beginning of the 2019, resulting in lower pressure levels in the facility. Thanks to this, it was possible to test three different channel geometries at different chamber background pressures. The results of the test were used to design a new engineering model of the thruster, to be tested by the end of the 2019. This paper presents the status of the activities on the SITAEL’s 20kW Hall Thruster propulsion system, as a part of converging efforts which are aimed at making such a propulsion system available for the space missions of the near future.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
