$3.1 million grant for Helicon Double Layer Thruster with 2013 target for deployment in space



ANU's Plasma Research Laboratory has $3.1 million in Australian government funding Helicon Double Layer Thruster (HDLT). If its work is successful, the HDLT driver could be in space as early as 2013 via a collaboration between the ANU, Surrey University's space centre, and aerospace firm EADS-Astrium.

The Helicon thruster has the edge on rival technologies as it is simpler and has been proven to work with many propellants including hydrogen, a waste product of human habitation.



The Helicon Double Layer Thruster has two main advantages over most other ion thruster designs; first, it creates an accelerating electric field without inserting unreliable components like high voltage grids into the plasma (the only plasma facing component is the robust plasma vessel). Secondly, a neutralizer isn't needed, since there are equal numbers of electrons and (singly-charged) positive ions emitted
