AB  - The performance of a novel neutralizer for space applications based on a E×B dischargeis  presented.   Preliminary  tests  were  carried  out  with  argon  gas  and  flow  rates  in  therange of 5-10 SCCM. Electrons were extracted through an orifice of diameter 1.8 mm.  Themaximum extracted current versus input power reported was 2.4 mA/W. The total powerinput, given by the sum of discharge power plus the extraction power, was in the range of40-90 W. During extraction tests, the discharge current was limited at 0.2 A due to limitin the cooling system.  Future work will be focused on tests at various extraction orificediameters and cathode materials.  Ultimately, xenon and non-conventional gases would betested as working gases.
