In August we carried out a helium test on version II and III of the Nassikas thruster at SuperPower Corp. in Schenectady, NY. We fixed the coil in a liquid helium dewar with its axis pointed in a horizontal direction. The dewar in turn was suspended from a ceiling beam so that it could move from side to side. Any side deflection of the dewar, due to any internally developed force, would have been measured on an electronic scale which was in mechanical contact with the wall of the dewar. More →
