A New Facility for Electrospray Propulsion Studies with Spatial Resolution of the Full Beam and High-Resolution Mass Analysis
Abstract
This is the final progress report on Yales AFOSR grant FA9550-18-1-0165, covering the full grant period from 6/1/2018 to 31/May/2022. Advances were made along four different lines: (1) Our main task, A new facility for electrospray propulsion studies with spatial resolution of the full beam and high-resolution mass analysis; (2) Studies on ionic liquid cluster fragmentation carried out in collaboration with Professor Paulo Lozano (MIT). This has included studies on a variety of instruments developed specifically for this task, using conventional and multiplexed mobility analyzers, and condensation particle counters; (3) The structure of magnetized conical tips; and (4) Propulsion based on heavy or multivalent ions, in collaboration with Dr. Kamran Ghiassi (Edwards Air Force Base). Along line 1, an instrument capable of characterizing full electrospray plumes in vacuum in terms of energy, mass/charge and angular distribution has been developed and undergone continuous refinement in resolving power and sensitivity. The instrument determines key jet characteristics such as energy dissipated, jet potential, diameter and velocity at the breakup point.
