Abstract

The time-of-flight measurement technique for beam parameters is studied to estimate polydispersity of sputtering for liquid working media in a colloidal electrojet thruster. The investigation is carried out using a module of the thruster equipped with 18 emission units. These 18 units generate in total the beam with 75 mm diameter on the outlet of the module. A kinetic efficiency value for the module varies in the 0.55..0.75 range depending on fluid flow rate and particle outlet velocity values.
