Several space applications indicate the possibility to adopt Mini Hall Thrusters, with discharge power in the range 50 to 200 W, among existing electric thruster propulsion technologies, to match mission propulsion requirements. A nominally 100W Hall Effect Thruster prototype (with an alumina acceleration chamber diameter slightly larger than 29 mm) has been recently designed and manufactured by Alta and Centrospazio, with the purpose of performing a wide range parametric exploration of the main engineering and physical aspects relevant to these devices at low power. During 2004 a preliminary experimental characterization has been performed in Alta's IV-4 test facility (in Pisa, Italy), a 2 m dia. 4 m length AISI 316 L vacuum chamber, equipped with a set of 6 tailored cryopumping surfaces with a total pumping speed on Xe in the order of 70000 l/s. Additional tests will be performed at ESA- ESTEC Electric Propulsion Laboratory (in the Netherlands).
